2-10|x+1|=-78

2 - 10 ∣ x + 1 ∣ = - 78

x = - 9 or x = 7

Solution steps

2 - 10 ∣ x + 1 ∣ = - 78

Move

2

to the right side

- 10 ∣ x + 1 ∣ = - 80

Divide both sides by

- 10

∣ x + 1 ∣ = 8

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x + 1 = - 8 or x + 1 = 8

x + 1 = - 8 or x + 1 = 8

x = - 9 or x = 7

∣ 3 w + 12 ∣ = 9

z - 10 = ∣ 7 z - 16 ∣

∣ x + 16 ∣ = 0.32, x

- 3 ∣ x - 7 ∣ - 9 = 27

- 3 ∣ 4 n - 9 ∣ = 24
