5|u+8|-70=-15

5 ∣ u + 8 ∣ - 70 = - 15

u = - 19 or u = 3

Solution steps

5 ∣ u + 8 ∣ - 70 = - 15

Move

70

to the right side

5 ∣ u + 8 ∣ = 55

Divide both sides by

5

∣ u + 8 ∣ = 11

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

u + 8 = - 11 or u + 8 = 11

u + 8 = - 11 or u + 8 = 11

u = - 19 or u = 3

2 ∣ k ∣ = 4

∣ 2 x + 13 ∣ = 28

∣ 9 x + 2 ∣ = 1

∣ u - 1 ∣ = 1

∣ - 7 g ∣ + 5 = 8
