∣ x - 1 ∣ + ∣ x + 1 ∣ = 2

- 1 \leq x \leq 1

Solution steps

∣ x - 1 ∣ + ∣ x + 1 ∣ = 2

Find positive and negative intervals

x < - 1, - 1 \leq x < 1, x \geq 1

Solve the inequality for each interval

No Solution or - 1 \leq x < 1 or x = 1

Merge Overlapping Intervals

- 1 \leq x \leq 1

∣ 5 y + 2 ∣ = 0

2 x^{2} - 4 = 8 x - 6

x^{2} - 5 x + 6 = 2 x - 3

\frac{( 4 w - 1 )}{6} = \frac{( 2 w )}{3} + \frac{1}{4}

∣ 2 x - 1 ∣ + x = 3
