Question

solve.
$5(2z + 8) = 30$

Explanation:

Step1: Divide both sides by 5

$\frac{5(2z + 8)}{5} = \frac{30}{5}$
Simplify to get: $2z + 8 = 6$

Step2: Subtract 8 from both sides

$2z + 8 - 8 = 6 - 8$
Simplify to get: $2z = -2$

Step3: Divide both sides by 2

$\frac{2z}{2} = \frac{-2}{2}$
Simplify to get: $z = -1$

Answer:

$z = -1$
