Question

1. an equation is shown.

6x - 3 = 3x + 12
what is the solution to the equation?

Explanation:

Step1: Subtract $3x$ from both sides

$6x - 3 - 3x = 3x + 12 - 3x$
$3x - 3 = 12$

Step2: Add 3 to both sides

$3x - 3 + 3 = 12 + 3$
$3x = 15$

Step3: Divide by 3 on both sides

$\frac{3x}{3} = \frac{15}{3}$
$x = 5$

Answer:

$x=5$
