3 ∣ 4 x - 8 ∣ = 9

x = \frac{5}{4} or x = \frac{11}{4}

Decimal Notation

x = 1.25, x = 2.75

Solution steps

3 ∣ 4 x - 8 ∣ = 9

Divide both sides by

3

∣ 4 x - 8 ∣ = 3

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

4 x - 8 = - 3 or 4 x - 8 = 3

4 x - 8 = - 3 or 4 x - 8 = 3

x = \frac{5}{4} or x = \frac{11}{4}

∣ 4 v + 8 ∣ = 4

12 = ∣ - 9 y ∣

∣ y ∣ + 9 = 15

5 ∣ x - 4 ∣ = 16

5 ∣ 1 - 2 x ∣ - 7 = 3
