10 ∣ - 7 x - 4 ∣ = 40

x = - \frac{8}{7} or x = 0

Decimal Notation

x = - 1.14285 \dots, x = 0

Solution steps

10 ∣ - 7 x - 4 ∣ = 40

Divide both sides by

10

∣ - 7 x - 4 ∣ = 4

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 7 x - 4 = - 4 or - 7 x - 4 = 4

- 7 x - 4 = - 4 or - 7 x - 4 = 4

x = - \frac{8}{7} or x = 0

∣ 3 x - 5 ∣ - 3 = 0

5 ∣ 2 x - 3 ∣ = 5

- 2 ∣ x + 2 ∣ + 19 = 7

- ∣ 4 + x ∣ = - 10

10 = ∣ 3 x - 5 ∣
