8 ∣ 8 x - 7 ∣ = 16

x = \frac{5}{8} or x = \frac{9}{8}

Decimal

x = 0.625, x = 1.125

Solution steps

8 ∣ 8 x - 7 ∣ = 16

Divide both sides by

8

∣ 8 x - 7 ∣ = 2

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

8 x - 7 = - 2 or 8 x - 7 = 2

8 x - 7 = - 2 or 8 x - 7 = 2

x = \frac{5}{8} or x = \frac{9}{8}

\frac{x}{6} = 4

∣ v ∣ + 11 = 15

6 - 2 ∣ 7 x - 3 ∣ = - 4

∣ x + 7 ∣ = 7

- 4 ∣ 2 v + 2 ∣ = 0
