2(7z - 6) = 44
answer
attempt 1 out of 2
z = submit answer

Explanation:

Step1: Dividir ambos lados por 2

$$\frac{2(7z - 6)}{2}=\frac{44}{2}$$
$$7z - 6 = 22$$

Step2: Sumar 6 a ambos lados

$$7z-6 + 6=22 + 6$$
$$7z=28$$

Step3: Dividir ambos lados por 7

$$\frac{7z}{7}=\frac{28}{7}$$
$$z = 4$$

Answer:

\(z = 4\)
