∣ 3 x ∣ + 8 = 17

x = - 3 or x = 3

Solution steps

∣ 3 x ∣ + 8 = 17

Move

8

to the right side

∣ 3 x ∣ = 9

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

3 x = - 9 or 3 x = 9

3 x = - 9 or 3 x = 9

x = - 3 or x = 3

x^{2} + 6 x - 8 = 8

∣ 5 x - 3 ∣ + 2 = 7

x^{2} - 13 = 3

- 2 ∣ x + 8 ∣ = 20

∣ 3 x - 5 ∣ = 2 - x
