9 ∣ 7 z + 5 ∣ = 27

z = - \frac{8}{7} or z = - \frac{2}{7}

Decimal Notation

z = - 1.14285 \dots, z = - 0.28571 \dots

Solution steps

9 ∣ 7 z + 5 ∣ = 27

Divide both sides by

9

∣ 7 z + 5 ∣ = 3

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

7 z + 5 = - 3 or 7 z + 5 = 3

7 z + 5 = - 3 or 7 z + 5 = 3

z = - \frac{8}{7} or z = - \frac{2}{7}

∣ 18 x - 5 ∣ = 0

3 ∣ 3 x - 11 ∣ = 21

92 = ∣ r - 900 ∣ - 8

2 - 9 ∣ - 5 x - 10 ∣ = - 88

∣ 5 x + 10 ∣ = 5
