∣ 20 + 2 x ∣ = ∣ 4 x + 4 ∣

x = - 4 or x = 8

Solution steps

∣ 20 + 2 x ∣ = ∣ 4 x + 4 ∣

Find positive and negative intervals

x < - 10, - 10 \leq x < - 1, x \geq - 1

Solve the inequality for each interval

No Solution or x = - 4 or x = 8

x = - 4 or x = 8

∣ x + 3 ∣ + ∣ x - 2 ∣ = 5

x^{2} + x + 1 + ∣ 2 x - 3 ∣ = 4 x

∣ - 13 ∣ + \frac{3 x + 6}{7} + ∣ 4 ∣ = 25

∣ x + 3 ∣ - ∣ 4 - x ∣ = ∣ 8 + x ∣

∣ x - 3 ∣ + ∣ x + 5 ∣ = 8
