x^{2} - 13 = 3

x = - 4 or x = - 10 or x = 10 or x = 4

Solution steps

x^{2} - 13 = 3

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x^{2} - 13 = - 3 or x^{2} - 13 = 3

x^{2} - 13 = - 3 or x^{2} - 13 = 3

(x = - 10 or x = 10) or (x = - 4 or x = 4)

x = - 4 or x = - 10 or x = 10 or x = 4

- 2 ∣ x + 8 ∣ = 20

∣ 3 x - 5 ∣ = 2 - x

5 ∣ x - 4 ∣ - 9 = 2

∣ 3 x + 5 ∣ + 8 = 7

- 3 = ∣ x ∣
