-|10+x|+10=-1

- ∣ 10 + x ∣ + 10 = - 1

x = - 21 or x = 1

Solution steps

- ∣ 10 + x ∣ + 10 = - 1

Move

10

to the right side

- ∣ 10 + x ∣ = - 11

Divide both sides by

- 1

∣ 10 + x ∣ = 11

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

10 + x = - 11 or 10 + x = 11

10 + x = - 11 or 10 + x = 11

x = - 21 or x = 1

- 92 = - 10 ∣ 2 - 4 n ∣ + 8

10 - 4 ∣ 4 x + 8 ∣ = - 26

- 3 ∣ x - 6 ∣ - 10 = - 31

4 = ∣ - 3 a + 4 ∣

∣ x - 3 ∣ + 9 = 30
