|(5x+20)/4 |=5

\frac{5 x + 20}{4} = 5

x = - 8 or x = 0

Solution steps

\frac{5 x + 20}{4} = 5

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

\frac{5 x + 20}{4} = - 5 or \frac{5 x + 20}{4} = 5

\frac{5 x + 20}{4} = - 5 or \frac{5 x + 20}{4} = 5

x = - 8 or x = 0

45 = ∣ c - 20 ∣

∣ x + 7 ∣ = - 2

∣ 4 + 3 x ∣ = 6

∣ 3 - 2 x ∣ = 5

∣ 2 x - 1 ∣ - 4 = x
