Solution steps

- 3 ∣ 5 x + 10 ∣ = - 20

Divide both sides by

- 3

∣ 5 x + 10 ∣ = \frac{20}{3}

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

5 x + 10 = - \frac{20}{3} or 5 x + 10 = \frac{20}{3}

5 x + 10 = - \frac{20}{3} or 5 x + 10 = \frac{20}{3}

x = - \frac{10}{3} or x = - \frac{2}{3}

1 = ∣ w - 7 ∣

∣ 20 x ∣ = 0

8 - 2 ∣ x + 2 ∣ = 5

2 ∣ 3 x + 3 ∣ - 10 = 32

x, ∣ 2 x - 1 ∣ = 9
