∣ - 3 z - 9 ∣ = 13

z = - \frac{22}{3} or z = \frac{4}{3}

Decimal Notation

z = - 7.33333 \dots, z = 1.33333 \dots

Solution steps

∣ - 3 z - 9 ∣ = 13

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 3 z - 9 = - 13 or - 3 z - 9 = 13

- 3 z - 9 = - 13 or - 3 z - 9 = 13

z = - \frac{22}{3} or z = \frac{4}{3}

4 = ∣ c + 3 ∣

20 = ∣ - 5 w ∣

∣ 3 - 2 t ∣ + 5 = 16

∣ 4 + 9 m ∣ + 4 = 8

∣ 2 k + 10 ∣ + 9 = 15
