Inverse operations are like "opposites", what undoes the operation. Multiplication and division are inverses, as are addition and subtraction. For example, if you have 4x+2=10, you have to use the inverse of addition (subtraction) to get rid of the 2. 4x+2=10 ...

To rewrite in Ax+By=C form, rearrange the terms so that x and y are on the left and the number is on the right. 5y-6=2x+3 Subtract 2x from both sides. -2x+5y-6=3 Add 6 to both sides. -2x+5y=9
