the hints dont make since to me when it says "subtract 2x from both sides" I dont know which 2 sides to subtract frombecause it doesnt show it just shows -y=-2x+2
Also it is the same thing with the "divide both sides by -1: it just shows the equation not where exactly they subtracted it from though and it seems that all the hint did was do the opposite of the original equation and switch the number placement around
