∣ 18 - 5 x ∣ = \frac{3}{4}

x = \frac{69}{20} or x = \frac{15}{4}

Decimal

x = 3.45, x = 3.75

Solution steps

∣ 18 - 5 x ∣ = \frac{3}{4}

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

18 - 5 x = - \frac{3}{4} or 18 - 5 x = \frac{3}{4}

18 - 5 x = - \frac{3}{4} or 18 - 5 x = \frac{3}{4}

x = \frac{69}{20} or x = \frac{15}{4}

∣ w - 2 c i ∣

2 ∣ x ∣ + 6 = 4

∣ 2 x + 7 ∣ + 3 = x - 1

∣ x + 1 ∣ + ∣ 2 x - 3 ∣ = 1

∣ 4 x + 4 ∣ = 14
