x = \frac{7}{10} or x = \frac{11}{10}

Decimal

x = 0.7, x = 1.1

Solution steps

∣ 10 x - 9 ∣ = 2

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

10 x - 9 = - 2 or 10 x - 9 = 2

10 x - 9 = - 2 or 10 x - 9 = 2

x = \frac{7}{10} or x = \frac{11}{10}

∣ r ∣ - 5 = - 5

∣ 4 - 2 x ∣ - 5 = 3

- 3 ∣ x - 2 ∣ + 4 = 6 x + 19

∣ x ∣ = b

∣ x ∣ = a
