-4|d+5|=-60

- 4 ∣ d + 5 ∣ = - 60

d = - 20 or d = 10

Solution steps

- 4 ∣ d + 5 ∣ = - 60

Divide both sides by

- 4

∣ d + 5 ∣ = 15

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

d + 5 = - 15 or d + 5 = 15

d + 5 = - 15 or d + 5 = 15

d = - 20 or d = 10

∣ 2 x - 3 x ∣ = 5

- 16 = - ∣ c ∣

∣ 6 x + 12 ∣ = 18

∣ - 2 k + 2 ∣ - 5 = - 5

- \frac{2}{3} ∣ 2 + x ∣ = 4
