2|2x-2|=16

2 ∣ 2 x - 2 ∣ = 16

x = - 3 or x = 5

Solution steps

2 ∣ 2 x - 2 ∣ = 16

Divide both sides by

2

∣ 2 x - 2 ∣ = 8

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 x - 2 = - 8 or 2 x - 2 = 8

2 x - 2 = - 8 or 2 x - 2 = 8

x = - 3 or x = 5

- 5 ∣ v + 220 ∣ = - 200

∣ 3 x - 2 ∣ = 4 + x

9 = ∣ p - 8 ∣

∣ - d ∣ = 65

\frac{n ∣ n ∣}{2} = 22
