Question

What is the answer to -7(z-6)=-70

Answer 1

-7(z - 6) = -70

-7z + 42 = -70
        - 42    -42

-7z = -112

-7z/-7 = -112/-7
z = 16

Answer: z = 16

Answer 2

Distribute to get rid of parentheses.                                     -7z+42= -70
Subtract 42 on both sides to get closer to isolating variable. -7z=-112
Divide -7 on both sides to finally isolate variable.                       z=16
Answer is z=16
