The picture is too small, but which equations can undo each other? Addition and Subtraction is Inverse Operations Multiplication and Division is Inverse Operations
( x + 1 )/ 3 = x + 2 Multiply 3 on both sides x + 1 = 3x + 6 Subtract 6 on both sides x - 5 = 3x Subtract x from both sides -5 = 2x Divide 2 from both sides x = -2.5
