2|b+4|=48

2 ∣ b + 4 ∣ = 48

b = - 28 or b = 20

Solution steps

2 ∣ b + 4 ∣ = 48

Divide both sides by

2

∣ b + 4 ∣ = 24

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

b + 4 = - 24 or b + 4 = 24

b + 4 = - 24 or b + 4 = 24

b = - 28 or b = 20

2 = ∣ 8 x + 10 ∣

∣ x - 7 ∣ = 21

∣ 5 x - 2 ∣ = 4 x

∣ x + 7.5 ∣ = 2.5

∣ s - 6 ∣ = 1
