18 - 1.4 ∣ x - 15 ∣ = 0

x = \frac{15}{7} or x = \frac{195}{7}

Decimal

x = 2.14285 \dots, x = 27.85714 \dots

Solution steps

18 - 1.4 ∣ x - 15 ∣ = 0

Multiply both sides by

10

180 - 14 ∣ x - 15 ∣ = 0

Move

180

to the right side

- 14 ∣ x - 15 ∣ = - 180

Divide both sides by

- 14

∣ x - 15 ∣ = \frac{90}{7}

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x - 15 = - \frac{90}{7} or x - 15 = \frac{90}{7}

x - 15 = - \frac{90}{7} or x - 15 = \frac{90}{7}

x = \frac{15}{7} or x = \frac{195}{7}

∣ x ∣ = 53.1

3 = - 2 \frac{1}{4} s - 5 + 3

∣ x - 4 ∣ = ∣ 3 x + 1 ∣

x = ∣ x - 2 ∣

3.4 ∣ 0.5 x - 42.1 ∣ = - 20.6
