∣ 8 z - 4 ∣ = 8

z = - \frac{1}{2} or z = \frac{3}{2}

Decimal Notation

z = - 0.5, z = 1.5

Solution steps

∣ 8 z - 4 ∣ = 8

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

8 z - 4 = - 8 or 8 z - 4 = 8

8 z - 4 = - 8 or 8 z - 4 = 8

z = - \frac{1}{2} or z = \frac{3}{2}

6 x + 4 = ∣ x - 8 ∣

∣ 2 x - 11 ∣ - 6 = - 5

3 ∣ 4 x + 6 ∣ = 24

- 3 ∣ x + 4 ∣ = 12

- 6 ∣ - 6 k - 6 ∣ = - 72
