- 12 = - 4 ∣ - 4 + 8 x ∣

x = \frac{1}{8} or x = \frac{7}{8}

Decimal

x = 0.125, x = 0.875

Solution steps

- 12 = - 4 ∣ - 4 + 8 x ∣

Switch sides

- 4 ∣ - 4 + 8 x ∣ = - 12

Divide both sides by

- 4

∣ - 4 + 8 x ∣ = 3

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 4 + 8 x = - 3 or - 4 + 8 x = 3

- 4 + 8 x = - 3 or - 4 + 8 x = 3

x = \frac{1}{8} or x = \frac{7}{8}

4 \times ∣ 2 x + 7 ∣ - 5 = 31

∣ 5 x - 1 ∣ = x + 4

8 = 2 ∣ x ∣ - 6

∣ x + 1 ∣ = 4 - ∣ 3 x - 2 ∣

∣ x - 5 ∣ = 0.02
