Problem: Solution:

1. p – (-2) = -9 Make the – (-2) into a positive

because two negative turn into

a positive.

2. p + 2 = - 9 Subtract the opposite of +2

-2 -2 Which would be -2, what you

0 -11 do to one side you have to do to other, so you have to -2 from -9 too.

After that you would check if you got the right answer. So -11 + 2 = -9. Then -9 = -9.
