∣ x - 0.4 ∣ = 3.8

x = - 3.4 or x = 4.2

Solution steps

∣ x - 0.4 ∣ = 3.8

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x - 0.4 = - 3.8 or x - 0.4 = 3.8

x - 0.4 = - 3.8 or x - 0.4 = 3.8

x = - 3.4 or x = 4.2

∣ x + 5 ∣ + 9 = 7

- 5 = - ∣ t + 3 ∣ + 5

6 x^{2} - x - 3 = - 3

∣ 2 x - 8 ∣ - 9 = - 5

∣ 4 x - 17 ∣ - 11 = - 3
