7|v|=18

7 ∣ v ∣ = 18

v = - \frac{18}{7} or v = \frac{18}{7}

Solution steps

7 ∣ v ∣ = 18

Divide both sides by

7

∣ v ∣ = \frac{18}{7}

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

v = - \frac{18}{7} or v = \frac{18}{7}

∣ x + 6 ∣ - 1 = 1

2 + ∣ 6 n + 10 ∣ = 16

∣ - 7 y + 29 ∣ = 20

∣ e ∣ = 1

3 ∣ 2 x - 1 ∣ + 4 = 22
