-0.3|5.6k|=-6.72

- 0.3 ∣ 5.6 k ∣ = - 6.72

k = - 4 or k = 4

Solution steps

- 0.3 ∣ 5.6 k ∣ = - 6.72

Multiply both sides by

100

- 30 ∣ 5.6 k ∣ = - 672

Divide both sides by

- 30

∣ 5.6 k ∣ = \frac{112}{5}

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

5.6 k = - \frac{112}{5} or 5.6 k = \frac{112}{5}

5.6 k = - \frac{112}{5} or 5.6 k = \frac{112}{5}

k = - 4 or k = 4

9 ∣ 4 p + 2 ∣ + 8 = - 35

x, 7 ∣ x - 2 ∣ = 6

∣ 1 + 3 x ∣ = 2

∣ 3 v + 9 ∣ = - 3

- 11 ∣ v + 13 ∣ = - 132
