x^{2} - 17 ∣ x ∣ + 72 = 0

x = - 9 or x = - 8 or x = 8 or x = 9

Solution steps

x^{2} - 17 ∣ x ∣ + 72 = 0

Find positive and negative intervals

x < 0, x \geq 0

Solve the inequality for each interval

(x = - 9 or x = - 8) or (x = 8 or x = 9)

x = - 9 or x = - 8 or x = 8 or x = 9

∣ 5 x - 7 ∣ - 12 = - 3

- 1 = - 4 ∣ x - 3 ∣

∣ 5 - 5 x ∣ = 2

∣ 3 a + 6 ∣ = ∣ 3 a - 8 ∣

\frac{7}{4} ∣ 3 x + 5 ∣ + 1 = 15
