∣ 7 - 3 x ∣ = 5

x = \frac{2}{3} or x = 4

Decimal Notation

x = 0.66666 \dots, x = 4

Solution steps

∣ 7 - 3 x ∣ = 5

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

7 - 3 x = - 5 or 7 - 3 x = 5

7 - 3 x = - 5 or 7 - 3 x = 5

x = \frac{2}{3} or x = 4

∣ 2 x + 7 ∣ - 5 = 0

∣ 2 x + 7 ∣ - 5 = 7

\frac{∣ x ∣ - 5}{3} = 2

y, x = ∣ y + 9 ∣

∣ - 2 x - 10 ∣ + 4 = 2
