| x/(10)|=2

\frac{x}{10} = 2

x = - 20 or x = 20

Solution steps

\frac{x}{10} = 2

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

\frac{x}{10} = - 2 or \frac{x}{10} = 2

\frac{x}{10} = - 2 or \frac{x}{10} = 2

x = - 20 or x = 20

2 ∣ x - 3 ∣ = 10

∣ 6 x - 7 ∣ + 3 = 12

- 2 ∣ x + 5 ∣ + 3 x = - 22

∣ 6 x - 12 ∣ = 18

5 ∣ 4 x ∣ = - 100
