|3x|=1

∣ 3 x ∣ = 1

x = - \frac{1}{3} or x = \frac{1}{3}

Decimal

x = - 0.33333 \dots, x = 0.33333 \dots

Solution steps

∣ 3 x ∣ = 1

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

3 x = - 1 or 3 x = 1

3 x = - 1 or 3 x = 1

x = - \frac{1}{3} or x = \frac{1}{3}

∣ 2 x - 1 ∣ = - x

x^{2} - 4 = ∣ x ∣ + 2

∣ 2 x - 5 ∣ = 25

- ∣ x + 2 ∣ - 1 = 0

3 ∣ 2 d + 9 ∣ + 13 = 10
