2| 1/5 x-2|=8

2 \frac{1}{5} x - 2 = 8

x = - 10 or x = 30

Solution steps

2 \frac{1}{5} x - 2 = 8

Divide both sides by

2

\frac{1}{5} x - 2 = 4

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

\frac{1}{5} x - 2 = - 4 or \frac{1}{5} x - 2 = 4

\frac{1}{5} x - 2 = - 4 or \frac{1}{5} x - 2 = 4

x = - 10 or x = 30

3 ∣ 2 x - 7 ∣ = 21

x^{2} - 4 = 4 + 2 x

∣ x ∣ = x^{2} + x - 63

2 = ∣ - g ∣

∣ x ∣ = x^{2} + x - 80
