∣ x + 1 ∣ + ∣ x + 2 ∣ = 3

x = - 3 or x = 0

Solution steps

∣ x + 1 ∣ + ∣ x + 2 ∣ = 3

Find positive and negative intervals

x < - 2, - 2 \leq x < - 1, x \geq - 1

Solve the inequality for each interval

x = - 3 or No Solution or x = 0

x = - 3 or x = 0

∣ x - 1 ∣ + x = 1

∣ x - a ∣ = ∣ x - 4 ∣

∣ 3 x - 2 ∣ = - 4

∣ x - 1 ∣ + ∣ 2 x - 4 ∣ = 5

6 x^{2} - 5 x - 1 = 5 x - 6 x^{2} + 1
