    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
    Subtract 2 from both sides.
    4x=8
    Divide (inverse of multiplication, the 4 is attached to the x by multiplication) both sides by 4
    x=2
