x = \frac{6}{7} or x = \frac{12}{7}

Decimal Notation

x = 0.85714 \dots, x = 1.71428 \dots

Solution steps

∣ - 9 + 7 x ∣ = 3

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 9 + 7 x = - 3 or - 9 + 7 x = 3

- 9 + 7 x = - 3 or - 9 + 7 x = 3

x = \frac{6}{7} or x = \frac{12}{7}

∣ 7 z - 6 ∣ = 0

5 - \frac{1}{3} x = 0

3 ∣ 8 s - 400 ∣ - 1 = - 1

x = - ∣ 5 - 2 x ∣ - 3

∣ 8 x + 2 ∣ = 50
