8 - 8 ∣ - 5 b + 4 ∣ = - 120

b = - \frac{12}{5} or b = 4

Solution steps

8 - 8 ∣ - 5 b + 4 ∣ = - 120

Move

8

to the right side

- 8 ∣ - 5 b + 4 ∣ = - 128

Divide both sides by

- 8

∣ - 5 b + 4 ∣ = 16

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 5 b + 4 = - 16 or - 5 b + 4 = 16

- 5 b + 4 = - 16 or - 5 b + 4 = 16

b = - \frac{12}{5} or b = 4

∣ 10 + 2 n ∣ = 28

x^{2} - 2 = x + 4

19 = ∣ - 3 x + 13 ∣

2 - 3 ∣ x - 4 ∣ = - 7

21 = ∣ c - 30 ∣
