x = - \frac{6}{7} or x = 0

Decimal Notation

x = - 0.85714 \dots, x = 0

Solution steps

7 ∣ - 7 x - 3 ∣ = 21

Divide both sides by

7

∣ - 7 x - 3 ∣ = 3

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 7 x - 3 = - 3 or - 7 x - 3 = 3

- 7 x - 3 = - 3 or - 7 x - 3 = 3

x = - \frac{6}{7} or x = 0

x^{2} - 11 ∣ x ∣ - 60 = 0

5 ∣ 2 x - 10 ∣ + 2 = 5757

5 ∣ 3 - 2 t ∣ = 6

∣ - 5 x + 3 ∣ = 1

3 ∣ 2 x - 6 ∣ + 2 = 2
