|3(x+1)+6|=15

∣ 3 (x + 1) + 6 ∣ = 15

x = - 8 or x = 2

Solution steps

∣ 3 (x + 1) + 6 ∣ = 15

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

3 (x + 1) + 6 = - 15 or 3 (x + 1) + 6 = 15

3 (x + 1) + 6 = - 15 or 3 (x + 1) + 6 = 15

x = - 8 or x = 2

∣ - 3 - 2 x ∣ = - x

\frac{1}{7} x + 2 - 6 = - 6

- 4 ∣ 5 x + 4 ∣ + 25 = 9

6 ∣ x - 3 ∣ = 42

∣ 5 x - 8 ∣ - 4 = - 2
