Question

resuelve para x. - 18 = 7(x - 6) - 3x reduce al máximo la respuesta.

Explanation:

Step1: Expand the right - hand side

$7(x - 6)-3x=7x-42 - 3x$

Step2: Combine like terms on the right - hand side

$7x-42 - 3x=(7x-3x)-42=4x-42$
So the equation becomes $-18 = 4x-42$

Step3: Add 42 to both sides

$-18 + 42=4x-42 + 42$
$24 = 4x$

Step4: Divide both sides by 4

$\frac{24}{4}=\frac{4x}{4}$
$x = 6$

Answer:

$x = 6$
