9 ∣ x + 1 ∣ - 10 = 1

x = - \frac{20}{9} or x = \frac{2}{9}

Decimal Notation

x = - 2.22222 \dots, x = 0.22222 \dots

Solution steps

9 ∣ x + 1 ∣ - 10 = 1

Move

10

to the right side

9 ∣ x + 1 ∣ = 11

Divide both sides by

9

∣ x + 1 ∣ = \frac{11}{9}

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x + 1 = - \frac{11}{9} or x + 1 = \frac{11}{9}

x + 1 = - \frac{11}{9} or x + 1 = \frac{11}{9}

x = - \frac{20}{9} or x = \frac{2}{9}

8 ∣ v + 1 ∣ = 48

∣ - 20 - 5 x ∣ - 70 = - 40

∣ 8 y + 2 ∣ - 17 = 0

∣ c - 6 ∣ = 3

∣ 8 x + 2 ∣ + 8 = 13
