Answer:

x = 6 or -9

Explanation:

Solving absolute value equations:

I 2x + 3 I = 15

To solve the absolute value equations, set the absolute value expression to negative value and positive value, then solve both the equation.

2x + 3 = 15 or 2x + 3 = -15

Subtract 3 from both sides,

2x = 15 - 3 ; 2x = -15 - 3

2x = 12 ; 2x = -18

Divide by 2,

x = 12÷2 ; x = -18 ÷ 2

x = 6 ; x = -9
