If x > 2, then 2x-1 + X + 2 = x + 1, x = 0 (rounding off) if 1 / 2 ≤ x ≤ 2, then constant holds. If - 1 < x < 1 / 2, then 1-2x + 2-x = x + 1, x = 1 / 2 (rounding off) if x ≤ - 1, 1-2x + 2-x = - X-1, x = 2 (rounding off), so the answer is 1 / 2 ≤ x ≤ 2. It takes a lot of time to choose me. Ask: it's very difficult? It's time to practice your brain

If 2 | 3x-1 | - 4 = 0, then x =?

2 | 3x-1 | - 4 = 0 | 3x-1 | = 2 so 3x-1 = 2 or 3x-1 = - 2 so x = 1 or x = - 1 / 3
