Question

Number 4 solve , thanks.

Answer 1

The answer is option 1

Explanation:

In order to find the value of z, you have to get rid of all the unrelated variable :

`7 - √(3z + 2) = 4`

`- √(3z + 2) = 4 - 7`

`- √(3z + 2) = - 3`

`√(3z + 2) = 3`

`3z + 2 = {3}^(2)`

`3z + 2 = 9`

`3z = 7`

`z = (7)/(3)`

Answer 2

I believe the correct answer is A
