Write an article based on this "Begin by solving one equation for either variable. Substitute your findings in Step 1 into the other equation. Solve for the other variable. Solve the second variable. Double check that the variables you have found work for both equations."
article: It doesn't matter which equation you decide to work with or even which variable you choose to solve for, as you should find the same solution no matter what. However, you do want to make the process as simple as possible. You should choose the equation that you think will be easiest to work with. For instance, if there is an equation where one of the coefficients is 1, such as x - 3y = 7, you would choose that as it will be easy to solve for 'x'. For example, let's say our equations are: x - 2y = 10 (equation A) and -3x -4y = 10 (equation B). You would choose to work with x - 2y = 10 because the coefficient of x in this equation is 1. Solving for x in equation A would meaning adding 2y to both sides. Therefore, x = 10 + 2y. For this step, you will need to insert (or substitute) your solution for 'x' into the other solution that you did not work with. This will allow you to find the other variable, in this case 'y'. Let's try it: Insert the 'x' of equation B into equation A: -3(10 + 2y) -4y = 10. You can see that we have taken 'x' out of the equation and inserted what 'x' equals. Now that you have removed one of the variables from the equation, you can solve for the other variable. This is is simply solving a regular one-variable linear equation. Let's solve ours: -3(10 + 2y) -4y = 10 so -30 -6y -4y = 10. Combine the y's: -30 - 10y = 10. Move the -30 over to the other side: -10y = 40. Solve for y: y = -4. To do this, plug your findings for 'y', or the first variable, into one of the equations. Then solve for the other variable, in this case 'x'. Let's try it: Solve for 'x' in equation A by plugging in y = -4: x - 2(-4) = 10. Simply the equation: x + 8 = 10. Solve for x: x = 2. Plug both of the variables into each equation to make sure that they create true equations. Let's see if ours work: Equation A: 2 - 2(-4) = 10 is TRUE. Equation B: -3(2) -4(-4) = 10 is TRUE.

Write an article based on this "Measure your head's circumference. Cut a strip of thin, flexible cardboard. Attach a coffee filter to the cardboard circle. Wrap white fabric or paper around the cardboard. Push the coffee filter through so the bottom becomes the top."
article: With a flexible measuring tape, like one you would find in sewing kit, take a measurement around your head. If you don't have this kind of measuring tape, a piece of string will work. Write down the number of inches your head measured. If you used string, make a mark on it noting the measurement. You'll use this measurement to create the band of the cap. If you want to make sure the cap isn't too tight, you may want to add a little extra length. Cut the strip to your head measurement length and about 2 inches wide. After you cut it, circle it around your head to make sure it's the right size. Trim it down or cut a longer strip as needed. Staple the strip into a circle. A cereal box is a good option for this step. With the cardboard circle sitting on the table, or counter, place a coffee filter inside it with open end up. Place 4 to 5 staples around the edge securing the filter to the cardboard circle. This wrap should extend about inch past each side of the cardboard. Fold the extra down over the rim of the cardboard on the top and bottom. Then glue it in place to make sure it stays folded. You want the hat to appear all white, so try to make sure the cardboard is not visible. To do this, either use thick enough paper or fabric, or considering making it double thick with two layers. If you used a white shirt to cut out the collar, you could use more fabric from this same shirt. The portion of the coffee filter that you stapled to the cardboard will be the top of the hat so the staples don't rest on your head. Allow all of the glue to dry before placing the hat on your head.

article:
Lay 1 bunch of celery sideways on a cutting board. Use a sharp kitchen knife to carefully cut off the top leafy parts and the white base that connects the stalks at the bottom. A bunch of celery typically contains about 8-9 individual celery stalks. Advocates of celery juice suggest drinking a glass of it in the morning on an empty stomach, although there is no research that shows this is any better than consuming it at any other time of the day. Hold a stalk of celery under a running tap and gently rub your fingers along it to remove dirt and any other substances. Repeat this for each stalk to clean them all. You can also put the stalks in a colander, if you have one that is big enough, and rinse them all at once.
