Question

PLEASE HELP ME

Solve for x: |2x + 12| = 18
x = 3, x = −3

x = 3, x = −15

x = 15, x = −15

x = −3, x = 15

Answer 1

Give me one sec to answer be back

Answer 2

x = 3 x = -15

Explanation:

|2x + 12| = 18

There are two solutions to an absolute value equation, one positive and one negative

2x+12 = 18 2x+12 = -18

Subtract 12 from each side

2x+12-12 = 18-12 2x+12-12 = -18-12

2x = 6 2x = -30

Divide by 2

2x/2 = 6/2 2x/2 = -30/2

x = 3 x = -15
