2-4|-4x-4|=-30

2 - 4 ∣ - 4 x - 4 ∣ = - 30

x = - 3 or x = 1

Solution steps

2 - 4 ∣ - 4 x - 4 ∣ = - 30

Move

2

to the right side

- 4 ∣ - 4 x - 4 ∣ = - 32

Divide both sides by

- 4

∣ - 4 x - 4 ∣ = 8

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 4 x - 4 = - 8 or - 4 x - 4 = 8

- 4 x - 4 = - 8 or - 4 x - 4 = 8

x = - 3 or x = 1

∣ x + 6 ∣ - 7 = 8

∣ 5 x + 60 ∣ = 10 x

3 ∣ x + 4 ∣ - 5 = x + 4

∣ 10 a - 8 ∣ = 78

∣ 4 x - 6 ∣ = 6
