4 ∣ k ∣ - 6 = 4

k = - \frac{5}{2} or k = \frac{5}{2}

Solution steps

4 ∣ k ∣ - 6 = 4

Move

6

to the right side

4 ∣ k ∣ = 10

Divide both sides by

4

∣ k ∣ = \frac{5}{2}

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

k = - \frac{5}{2} or k = \frac{5}{2}

∣ 6 y + 3 ∣ = 9

- 2 + ∣ x + 3 ∣ = 2

∣ x - 8 ∣ - 8 = 14

- 3 ∣ 3 t - 4 ∣ - 12 = 6
