∣ - 7 x ∣ - 9 = - 5

x = - \frac{4}{7} or x = \frac{4}{7}

Decimal

x = - 0.57142 \dots, x = 0.57142 \dots

Solution steps

∣ - 7 x ∣ - 9 = - 5

Move

9

to the right side

∣ - 7 x ∣ = 4

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

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

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

x = - \frac{4}{7} or x = \frac{4}{7}

∣ 3 x + 7 ∣ = 2 x - 3

∣ n - 5 ∣ = 3

x^{2} + x - 5 = x^{2} + 5

26 = ∣ u ∣ - 9

2 ∣ x + 3 ∣ = 12
