Question

what is the solution to this equation?
7x - 3(x - 6) = 30
a. x = 3
b. x = 6
c. x = 9
d. x = 12

Explanation:

Step1: Expand the parentheses

$7x - 3x + 18 = 30$

Step2: Combine like terms

$4x + 18 = 30$

Step3: Isolate the variable term

$4x = 30 - 18$
$4x = 12$

Step4: Solve for $x$

$x = \frac{12}{4}$
$x = 3$

Answer:

A. $x=3$
