-3| v/9 |=-2

- 3 \frac{v}{9} = - 2

v = - 6 or v = 6

Solution steps

- 3 \frac{v}{9} = - 2

Divide both sides by

- 3

\frac{v}{9} = \frac{2}{3}

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

\frac{v}{9} = - \frac{2}{3} or \frac{v}{9} = \frac{2}{3}

\frac{v}{9} = - \frac{2}{3} or \frac{v}{9} = \frac{2}{3}

v = - 6 or v = 6

∣ 3 x - 8 ∣ + 2 = 9

∣ Y ∣ = 3

\frac{x - 1}{2} = 7

∣ 8 x - 1 ∣ = 9

2 ∣ 2 x - 3 ∣ = \frac{5}{2}
