question
solve.
4(2z - 8) = 16
answer attempt 1 out of 5
z = submit answer

Explanation:

Step1: Divide both sides by 4

$$\frac{4(2z - 8)}{4}=\frac{16}{4}$$
$$2z-8 = 4$$

Step2: Add 8 to both sides

$$2z-8 + 8=4 + 8$$
$$2z=12$$

Step3: Divide both sides by 2

$$\frac{2z}{2}=\frac{12}{2}$$
$$z = 6$$

Answer:

$$z = 6$$
