Question

Solve for z.

–9 + 8(14z + 2) = 7(17z + 8)

z =

Answer 1

z=-7

Explanation:

-9+8*14z+8*2=7*17z+7*8

-9+112z+16=119z+56

112z+7=119z+56

-112z -112z

7=7z+56

-56 -56

-49=7z

:7 :7

z=-7

Answer 2

`\boxed{z = -7}`

Explanation:

`= > - 9 + 8(14z + 2) = 7(17z + 8) \\ \\ = > - 9 + (8 * 14z + 8 * 2) = (7 * 17z) + (7 * 8) \\ \\ = > - 9 + 112z + 16 = 119z + 56 \\ \\ = > 7 + 112z = 119z + 56\\ \\ = > 7 + 112z - 119z = 56 \\ \\ = > 7 - 7z = 56 \\ \\ = > - 7z = 56 - 7 \\ \\ = > - 7z = 49 \\ \\ = > 7z = - 49 \\ \\ = > z = - (49)/(7) \\ \\ = > z = - 7`
