|3x| + x = 2
|3x| = 2 - x
so by definition, 2-x ≥ 0
-x ≥ -2
x ≤ 2
3x = 2-x or -3x = 2-x
4x = 2 or -2x = 2
x = 1/2 or x = -1 , since both satisfy our intial restriction of x ≤ 2
x = 1/2 OR x = -1
|3x| = 2 - x
so by definition, 2-x ≥ 0
-x ≥ -2
x ≤ 2
3x = 2-x or -3x = 2-x
4x = 2 or -2x = 2
x = 1/2 or x = -1 , since both satisfy our intial restriction of x ≤ 2
x = 1/2 OR x = -1
