    -7 (z - 6) = - 70

    -7z + 42 = - 70

    - 42 - 42

    -7z = - 112

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

    z = 16

    Answer: z = 16

    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
