∣ 3 (x + 4) - 7 ∣ = 20

x = - \frac{25}{3} or x = 5

Decimal

x = - 8.33333 \dots, x = 5

Solution steps

∣ 3 (x + 4) - 7 ∣ = 20

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

3 (x + 4) - 7 = - 20 or 3 (x + 4) - 7 = 20

3 (x + 4) - 7 = - 20 or 3 (x + 4) - 7 = 20

x = - \frac{25}{3} or x = 5

∣ 2 x - 9 ∣ = ∣ x - 6 ∣

∣ 3 k - 8 ∣ = 4

∣ x - 19 ∣ = x^{2} - 19 x

2 x - x^{2} + 3 = 0

∣ 2 x - 1 ∣ - 5 = - 3
