∣ 10 xx - 7 ∣ = 5

x = - \frac{6}{5} or x = - \frac{1}{5} or x = \frac{1}{5} or x = \frac{6}{5}

Decimal Notation

x = - 1.09544 \dots, x = - 0.4472135955, x = 0.4472135955, x = 1.09544 \dots

Solution steps

∣ 10 xx - 7 ∣ = 5

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

10 xx - 7 = - 5 or 10 xx - 7 = 5

10 xx - 7 = - 5 or 10 xx - 7 = 5

(x = - \frac{1}{5} or x = \frac{1}{5}) or (x = - \frac{6}{5} or x = \frac{6}{5})

x = - \frac{6}{5} or x = - \frac{1}{5} or x = \frac{1}{5} or x = \frac{6}{5}

\frac{X + 8}{3} = 7

∣ 5 x + 5 ∣ - 16 = 0

∣ - 5 y ∣ - 8 = 2

∣ 4 x + 5 ∣ = x + 6

∣ 4 x + 5 ∣ = x + 5
