∣ x - 142 ∣ = 4

x = 138 or x = 146

Solution steps

∣ x - 142 ∣ = 4

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x - 142 = - 4 or x - 142 = 4

x - 142 = - 4 or x - 142 = 4

x = 138 or x = 146

- 4 ∣ 2 x + 6 ∣ = - 32

5 ∣ 7 - 7 g ∣ = - 20

∣ x ∣ + 6 = 18

∣ x + 3 ∣ + ∣ 3 x - 6 ∣ = 2 + x

3 ∣ 2 x - 7 ∣ - 4 = - 1
