= balance = It is important to understand that every equation is a balancing situation. Everything on the left of the equal sign must be equal to everything on the right. Whatever you do to the right you MUST do to the left.

ISOLATE the VARIABLE The INVERSE operation of addition is subtraction! Use the Inverse to Isolate the Variable B + 7 = 12 - 7 - 7 0 5 B = 5

4
ISOLATE the VARIABLE The INVERSE operation of multiplication is division! Use the Inverse to Isolate the Variable B x 7 = 14 7 2 B = 2
