substitute

-7 – q, q = -15

-7 – (-15), keep change opposite

-7 + 15; opposite signs subtract and keep the sign of the bigger #

8

-5 – f, f = 12

-5 – 12, keep change opposite

-5 + -12, same signs add and keep the sign

-17

-7-q for q= -15

you would take q and substitute it in. -7-(-15)

then simpify. -7+15

then solve. 8

-5-f for f=12

substitute. -5-12

easier understanding. -5 + (-12)

solve. -17
