Question

4z + 5 = -3z - 8
Z =

Answer 1

4z+5= -3z-8
4z+3z= -8-5
7z= -13
z= -13/7

Answer 2

`z = - (13)/(7)`

Explanation:

1) Add 3z to both sides.

`4 z+ 5 + 3z = - 8`

2) Simplify 4z + 4 + 3z to 7z + 5.

`7z + 5 = - 8`

3) Subtract 5 from both sides.

`7z = - 8 - 5`

4) Simplify -8-5 to -13.

`7z = - 13`

5) Divide both sides by 7.

`z = - (13)/(7)`

Therefore, the answer is z = - 13/7.
