question
solve for x.
4(2x - 1) + 4x - 4 = -32
answer attempt 1 out of 9

Explanation:

Step1: Expandir la expresión

$$4(2x - 1)+4x - 4=-32$$
$$8x-4 + 4x-4=-32$$

Step2: Combinar términos semejantes

$$(8x + 4x)+(-4-4)=-32$$
$$12x-8=-32$$

Step3: Añadir 8 a ambos lados

$$12x-8 + 8=-32 + 8$$
$$12x=-24$$

Step4: Dividir por 12

$$\frac{12x}{12}=\frac{-24}{12}$$
$$x=-2$$

Answer:

\(x = - 2\)
