8 - ∣ 8 - 9 x ∣ = - 7

x = - \frac{7}{9} or x = \frac{23}{9}

Decimal Notation

x = - 0.77777 \dots, x = 2.55555 \dots

Solution steps

8 - ∣ 8 - 9 x ∣ = - 7

Move

8

to the right side

- ∣ 8 - 9 x ∣ = - 15

Divide both sides by

- 1

∣ 8 - 9 x ∣ = 15

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

8 - 9 x = - 15 or 8 - 9 x = 15

8 - 9 x = - 15 or 8 - 9 x = 15

x = - \frac{7}{9} or x = \frac{23}{9}

∣ x - 5 ∣ + 7 = 15

2 x^{2} - x - 1 = 3

- 14 - 11 ∣ - 9 + 6 x ∣ = - 13

x^{2} - 5 ∣ x ∣ - 6 = 0

x, y = f ∣ x ∣
