\frac{1}{3} ∣ 3 x + 8 ∣ + 4 = 8

x = - \frac{20}{3} or x = \frac{4}{3}

Decimal

x = - 6.66666 \dots, x = 1.33333 \dots

Solution steps

\frac{1}{3} ∣ 3 x + 8 ∣ + 4 = 8

Move

4

to the right side

\frac{1}{3} ∣ 3 x + 8 ∣ = 4

Multiply both sides by

3

∣ 3 x + 8 ∣ = 12

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

3 x + 8 = - 12 or 3 x + 8 = 12

3 x + 8 = - 12 or 3 x + 8 = 12

x = - \frac{20}{3} or x = \frac{4}{3}

∣ x + 3 ∣ + 2 ∣ x ∣ = 4

∣ x - 2 ∣ = ∣ - 6 ∣

\frac{k}{6} = 4

- 5 ∣ 6 x - 8 ∣ = - 10

∣ 2 x - 4 ∣ = 22
