Question 954031: If x - y = -15 and I have the numbers on the table the thing I have a problem with is getting y by itself like my math teacher told me to (Pre Algebra) could you like explain to me how to get y by itself so I can find the y by doing the stuff to x
x-y
2,y
1,y
0,y
-1,y

You might try putting everything on one side:
x-y=-15 Add 15 to each side.
x-y+15=0 Now just cancel the y on the non-zero side, it winds up alone on the other side. Add y to each side.
x+15=y
