Question

Solve. 2(2z – 4) = 4​

Answer 1

`z = 3`

Explanation:

1) Divide both sides by 2.

`2z - 4 = (4)/(2)`

2) Simplify 4/2 to 2.

`2z - 4 = 2`

3) Add 4 to both sides.

`2z = 2 + 4`

4) Simplify 2 + 4 to 6.

`2z = 6`

5) Divide both sides by 2.

`z = (6)/(2)`

6) Simplify 6/2 to 3.

`z = 3`

therefor, the answer is z = 3.
