Answer:

z=16

Step-by-step explanation:

-7(z-6)= -70

combine -7 with the bracket

-7z + 42 = -70

      -42        -42

-7z = - 112

divide both sides by -7

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

z = 16

check

-7(z-6)= -70

-7(16-6)= -70

combine

-112+42= -70

  -42         -42

-112 = -112

Divide both sides by -7
z-6=10

Add 6 to both sides
z=16

Hope this helps!
