Question

2|x+3|=4

Answer 1

2 | x + 3 | = 4 --- divide both sides by 2
| x + 3 | = 2

(x + 3) = 2 -- subtract 3 from both sides
x = 2 - 3
x = -1

-(x + 3) = 2 -- distribute
-x - 3 = 2 -- add 3 to both sides
-x = 3 + 2
-x = 5 -- multiply by -1 to make x positive
x = -5

solutions are : x = -1 and x = -5
