|3x-4|=1

∣ 3 x - 4 ∣ = 1

x = 1 or x = \frac{5}{3}

Decimal Notation

x = 1, x = 1.66666 \dots

Solution steps

∣ 3 x - 4 ∣ = 1

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

3 x - 4 = - 1 or 3 x - 4 = 1

3 x - 4 = - 1 or 3 x - 4 = 1

x = 1 or x = \frac{5}{3}

∣ x - 4 ∣ = - 2

x^{2} - 2 = 2

x^{2} - x - 3 = 3

∣ - 4 + 2 x ∣ = 2

x, ∣ x - y ∣ = 0
