Summarize the following:
It doesn't matter which equation you choose, but you might want to look for one that will give you numbers that are easier to work with. For example, if your simultaneous equations are 1) x+2y=4{\displaystyle x+2y=-4} and 2) 2x+5y=1{\displaystyle 2x+5y=1}, you will probably want to begin with the first equation, because the x{\displaystyle x} is already by itself. You could also start by isolating the y variable (or whatever other variable the equation uses). For example, if you are beginning with x+2y=4{\displaystyle x+2y=-4}, you could solve for x{\displaystyle x} by subtracting 2y from each side.x+2y=4{\displaystyle x+2y=-4}x=42y{\displaystyle x=-4-2y} Place the value in parentheses for clarity. For example, if you found x=42y{\displaystyle x=-4-2y} in the first equation, plug in 42y{\displaystyle -4-2y} for x{\displaystyle x} in the second equation:2x+5y=1{\displaystyle 2x+5y=1}2(42y)+5y=1{\displaystyle 2(-4-2y)+5y=1} Remember to follow the order of operations. For example, to solve for y{\displaystyle y} in the equation 2(42y)+5=1{\displaystyle 2(-4-2y)+5=1}, first use the distributive property to multiply.2(42y)+5y=1{\displaystyle 2(-4-2y)+5y=1}84y+5y=1{\displaystyle -8-4y+5y=1}8+y=1{\displaystyle -8+y=1}y=9{\displaystyle y=9}

summary: Choose the equation you want to work with first. Isolate the x{\displaystyle x} variable in the first equation. Plug in the value of x{\displaystyle x} into the second equation. Find the value of y{\displaystyle y} in the second equation.

A single-color t-shirt will add contrast to your outfit while keeping it simple. Light colored jackets can be offset with dark colored shirt choices and vice versa. Wear a graphic tee for a trendier look. When selecting a graphic tee or similar shirts, choose ones with designs on the front-middle of the shirt. This way others can see the design when your jacket's unbuttoned. When wearing a tee, elaborate shoes might clash with your casual look. Try sneakers, simple boat shoes, or a casual, low-cut boot. Simple patterns, like horizontal stripes, can add pop to your ensemble. More complex patterns, like paisley, may draw attention away from your jacket. Jean jackets are often associated with rugged cowboys and rural farmers. Emphasize these qualities with plaid and simple checked patterns. Shirts made of flannel fabric are also an excellent choice for the rustic look. To complete your rustic appearance, wear a cowboy hat and some cowboy boots. Try not to over accessorize, as this may come across as though you're trying too hard to look the part. If the color or the style of the denim of your jacket and pants don't match, these may end up clashing. Get around the matching problem by wearing black jeans with your jean jacket. Keep this look simple and refined with a pair of brown shoes or low cut boots. Wear sneakers to dress this look down. Khaki pants will provide a casual, laid-back look with nearly any shirt and jean jacket combo. Traditional khakis will suit blue and black jackets. Khakis dyed non-traditional colors can add some variety to an everyday outfit. Pair traditional khakis with a jean jacket and a button down shirt for a look that might be described as "rugged gentleman." Brown accessories, like belts and bracelets, and brown footwear, like derbies and oxfords, work well with traditional khaki pants. Oxblood colors add a rich, refined warmth to this look.

summary: Keep casual with a t-shirt. Play up the rustic qualities of your jacket. Match denim pants with your jacket carefully. Choose khaki pants for a versatile outfit.

Pour rubbing alcohol onto the spill in a puddle. Leave it to soak in for 30 minutes. Once it's had time to soak, wipe up the spill using paper towels, scrubbing gently over the paint. It should come right up. Test the rubbing alcohol first on an inconspicuous corner if you have tile. If you have a dried paint spill on wood, apply a citrus-based cleaner such as Goo Gone. Let it soak for a minute or 2, and then use a gentle brush on it. You may need to reapply it several times. Don't let it soak too long, as the cleaner could stain the floor. Don't use an abrasive brush or scraper, as you can damage the wood. With carpet, try using a scrubbing brush to flake the paint off the carpet, and then vacuum the paint off. You may also be able to use needle-nose pliers to pull out clumps. If all else fails, try cutting the carpet with scissors right at the top where the splatter is. Chemicals that remove paint will likely cause damage to your carpet, but you can try them in a hidden corner first. If they don't cause damage, you can use them to remove paint. If you know you have metal debris, such as nails, bolts, or even metal shavings, try renting or buying a magnetic sweeper. You just roll the sweeper over the area, and it attracts any metal debris with a magnet. Then, you pull up on the handle on top of the sweeper head to release the metal pieces into the trash. It's a good idea to put these items in a solid container if you plan on throwing them away. If you have any broken glass, start by carefully picking up the large pieces. Wear protective gloves for this task. Then, for smaller pieces, try cutting a potato in half. Press the cut side into the glass to pick up little shards. Sweep up anything that remains. Place any broken glass in a solid container, such as a coffee can, before putting it in the trash. If you need to scrub down an area that's going to take a lot of work because of construction dirt or debris, try getting a brush attachment for your drill. That way, the drill can do the majority of the scrubbing for you.
summary: Apply rubbing alcohol to a dry latex paint spill on tile or linoleum. Use a citrus-based cleaner on wood. Pick paint off of carpet. Use a magnetic sweeper to pick up nails. Remove broken glass. Add a brush to a drill to scrub an area thoroughly.
