∣ x ∣ = \frac{1}{7}

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

Decimal Notation

x = - 0.14285 \dots, x = 0.14285 \dots

Solution steps

∣ x ∣ = \frac{1}{7}

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

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

∣ x ∣ - 7 = 1

∣ 2 x + 1 ∣ = 6 x - 11

∣ x + 2 ∣ + 6 = 3 x

2 ∣ x - 3 ∣ + x = 8

∣ 3 x - 15 ∣ = 8
