Move

5

to the right side

∣ - 9 b + 6 ∣ = 12

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 9 b + 6 = - 12 or - 9 b + 6 = 12

- 9 b + 6 = - 12 or - 9 b + 6 = 12

b = - \frac{2}{3} or b = 2

∣ 2 x + 8 ∣ + 50 = 2

∣ 2 x + 7 ∣ = 6 x + 13

∣ 7 x - 12 ∣ = 23

0 = ∣ 4 - x ∣

∣ - 2 a + 1 ∣ = 3
