Question

Solve for x: −3|2x + 6| = −12

Answer 1

If you divide by -3, you'll have |2x+6| = 4.
We can also factor out a 2, and divide that on both sides, to have |x+3|=2.

Now it's really easy. The absolute value bars mean that x+3 could either be a positive 2 or a -2 and it would still satisfy the equation.

if x+3 = -2, then x = -5.
if x+3 = 2, then x = -1.

Answer 2

thank you
