2|-3x-12|-10=8

2 ∣ - 3 x - 12 ∣ - 10 = 8

x = - 7 or x = - 1

Solution steps

2 ∣ - 3 x - 12 ∣ - 10 = 8

Move

10

to the right side

2 ∣ - 3 x - 12 ∣ = 18

Divide both sides by

2

∣ - 3 x - 12 ∣ = 9

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 3 x - 12 = - 9 or - 3 x - 12 = 9

- 3 x - 12 = - 9 or - 3 x - 12 = 9

x = - 7 or x = - 1

∣ 7 x - 5 ∣ - 10 = - 10

∣ 2 - x ∣ = 0

∣ x + 7 ∣ = 1

∣ x - 5 ∣ = 3 x + 3

∣ - 2 x + 7 ∣ = 25
