∣ 15 - 9 x ∣ = 48

x = - \frac{11}{3} or x = 7

Solution steps

∣ 15 - 9 x ∣ = 48

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

15 - 9 x = - 48 or 15 - 9 x = 48

15 - 9 x = - 48 or 15 - 9 x = 48

x = - \frac{11}{3} or x = 7

∣ 6 x + 72 ∣ = 12 x

x^{2} + 4 x - 16 = 16

∣ - 4 d + 6 ∣ = 12

4 - 2 ∣ 10 x - 1 ∣ = 11

∣ x - 3 ∣ + 9 = 5
