Explanation:

Step1: Split absolute value equation

$3x + 3 = 30$ or $3x + 3 = -30$

Step2: Solve first linear equation

Subtract 3, then divide by 3:
$3x = 30 - 3 = 27$
$x = \frac{27}{3} = 9$

Step3: Solve second linear equation

Subtract 3, then divide by 3:
$3x = -30 - 3 = -33$
$x = \frac{-33}{3} = -11$

Answer:

$9, -11$
