|2x + 12| = 18

First, break down the problem into 2 equations . / 2x + 12 = 18 and -(2x + 12) = 18
Second, solve the first equation. /

Subtract 12 from both sides. / 2x = 18 - 12

Subtract 18 - 16. / 2x = 6

Divide both sides by 2. / $x = \frac{6}{2}$
Simplify. / x = 3

Third, solve the second equation. / -(2x + 12) = 18
Simplify your brackets. / -2x - 12 = 18

Add 12 to both sides. / -2x = 18 + 12

Add 18 + 12. / -2x = 30

Divide both sides by -2. / $x = \frac{30}{-2}$
Simplify. / $x = -\frac{30}{2}$
Simplify. / x = -15

Fourth, collect the solutions. / x = -15,3

x = -15, 3
