2|3x+1|-5 = 11 add 5 to both sides of the equation:
2|3x+1| = 16 divide both sides by 2:
|3x+1| = 8 now we remove the bars and we get:
3x+1 = 8 or 3x+1 = -8 subtract 1, all sides:
3x = 7 or 3x = -9 Divide all by 3
x = 7/3 or x = -9/3
x = 2 1/3 or x = -3

2abs%283x%2B1%29=16

abs%283x%2B1%29=8

Either 3x+1 is non-negative or negative. Solve for both cases.
