2|2x+4|=32

2 ∣ 2 x + 4 ∣ = 32

x = - 10 or x = 6

Solution steps

2 ∣ 2 x + 4 ∣ = 32

Divide both sides by

2

∣ 2 x + 4 ∣ = 16

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 x + 4 = - 16 or 2 x + 4 = 16

2 x + 4 = - 16 or 2 x + 4 = 16

x = - 10 or x = 6

- 9.28 x^{2} + ∣ 9 x ∣ = 2

3 ∣ 9 - 8 x ∣ = x

2 ∣ 4 - 9 x ∣ = 9 x - 7

k ∣ k + 8 ∣ = 8

∣ 9 x ∣ = 27
