Question

Write an expression that equals (x-13). It must have atleast 2 sets of parentheses and one minus sign. Verify that it is equal to (x-13).

Answer 1

(-X-13)+(X+13)+(X-13)

The positive x and negative x cancel out and equal zero. The positive 13 and negative 13 cancel and equal zero also. Then you are left with (x-13)
