x = \frac{2}{7} or x = \frac{4}{7}

Decimal

x = 0.28571 \dots, x = 0.57142 \dots

Solution steps

∣ - 7 x + 3 ∣ = 1

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 7 x + 3 = - 1 or - 7 x + 3 = 1

- 7 x + 3 = - 1 or - 7 x + 3 = 1

x = \frac{2}{7} or x = \frac{4}{7}

12 + ∣ 3 x + 7 ∣ = 0

∣ z - 8 ∣ = ∣ z + 8 ∣

∣ x - 2 ∣ = - 7

∣ 3 x - 8 ∣ = ∣ 6 x + 10 ∣

- 8 ∣ 5 p + 10 ∣ - 6 = - 86
