Move

3

to the right side

- 10 ∣ 5 k - 4 ∣ = - 90

Divide both sides by

- 10

∣ 5 k - 4 ∣ = 9

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

5 k - 4 = - 9 or 5 k - 4 = 9

5 k - 4 = - 9 or 5 k - 4 = 9

k = - 1 or k = \frac{13}{5}

∣ d - 93 ∣ = 1.5

2 x^{2} - 3 x - 14 = 8

∣ x + 9 ∣ - 1 = 4

∣ 3 x - 1 ∣ + x = 11

∣ 5 s ∣ = 20
