10 = ∣ - 7 x - 1 ∣ 5

x = - \frac{3}{7} or x = \frac{1}{7}

Decimal Notation

x = - 0.42857 \dots, x = 0.14285 \dots

Solution steps

10 = ∣ - 7 x - 1 ∣ \cdot 5

Switch sides

∣ - 7 x - 1 ∣ \cdot 5 = 10

Divide both sides by

5

∣ - 7 x - 1 ∣ = 2

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 7 x - 1 = - 2 or - 7 x - 1 = 2

- 7 x - 1 = - 2 or - 7 x - 1 = 2

x = - \frac{3}{7} or x = \frac{1}{7}

y (x - ∣ x ∣) = 1

2 ∣ x + 1 ∣ = 8 x - 4

∣ 5 - 6 n ∣ = - 31

7 ∣ 2 x - 5 ∣ = 49

5 ∣ 13 - 2 t ∣ = 25
