3| x/3 |-9=1

3 \frac{x}{3} - 9 = 1

x = - 10 or x = 10

Solution steps

3 \frac{x}{3} - 9 = 1

Move

9

to the right side

3 \frac{x}{3} = 10

Divide both sides by

3

\frac{x}{3} = \frac{10}{3}

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

\frac{x}{3} = - \frac{10}{3} or \frac{x}{3} = \frac{10}{3}

\frac{x}{3} = - \frac{10}{3} or \frac{x}{3} = \frac{10}{3}

x = - 10 or x = 10

∣ x + 2 ∣ = 2 x + 10

∣ f ∣ - 2 = 61

- 20 = - 5 ∣ d ∣

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

- 5 = 5 ∣ c ∣
