∣ - 2 b + 2 ∣ = 13

b = - \frac{11}{2} or b = \frac{15}{2}

Solution steps

∣ - 2 b + 2 ∣ = 13

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 2 b + 2 = - 13 or - 2 b + 2 = 13

- 2 b + 2 = - 13 or - 2 b + 2 = 13

b = - \frac{11}{2} or b = \frac{15}{2}

22 = ∣ - 2 + 5 y ∣

∣ 2 x - 3 ∣ = - x + 1

- 4 ∣ 2 x - 5 ∣ + 5 = - 19

∣ 9 - 3 c ∣ = 4

∣ 5 x - 6 ∣ - 4 = 10
