13 = ∣ - 2 b + 2 ∣

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

Decimal

b = - 5.5, b = 7.5

Solution steps

13 = ∣ - 2 b + 2 ∣

Switch sides

∣ - 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}

\frac{x}{2} - 5 = 4

∣ 3 x - 1 ∣ + 2 = x

\frac{∣ 2 x - 1 ∣}{3} = 5

∣ x + 2 ∣ + 8 = 7

∣ x + 3 ∣ = - 3 x + 7
