b = \frac{1}{2} or b = 3

Decimal

b = 0.5, b = 3

Solution steps

∣ 7 - 4 b ∣ = 5

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

7 - 4 b = - 5 or 7 - 4 b = 5

7 - 4 b = - 5 or 7 - 4 b = 5

b = \frac{1}{2} or b = 3

2 ∣ x - 6 ∣ + 14 = 38

∣ 6 v + 9 ∣ = 3

∣ 5 x + 3 ∣ - 4 = - 2

\frac{2}{3} x + 2 - 8 = 0

∣ 3 (x + 1) + 6 ∣ = 15
