3 ∣ 3 x - 5 ∣ = 30

x = - \frac{5}{3} or x = 5

Solution steps

3 ∣ 3 x - 5 ∣ = 30

Divide both sides by

3

∣ 3 x - 5 ∣ = 10

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

3 x - 5 = - 10 or 3 x - 5 = 10

3 x - 5 = - 10 or 3 x - 5 = 10

x = - \frac{5}{3} or x = 5

2 ∣ x + 1 ∣ + x = 1

x^{2} - 10 x + 9 = 0

2 - ∣ 4 - x ∣ = 0

∣ - 11 x + 3 ∣ + 7 = 2

∣ x - 8 ∣ = 0.01
