v = - 11 or v = 4

Solution steps

∣ 2 v + 7 ∣ - 30 = - 15

Move

30

to the right side

∣ 2 v + 7 ∣ = 15

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 v + 7 = - 15 or 2 v + 7 = 15

2 v + 7 = - 15 or 2 v + 7 = 15

v = - 11 or v = 4

2 x + 3 = - ∣ x + 1 ∣ - 1

x^{2} - 1 = 2 x

∣ 1 - 2 t ∣ + 3 = 8

- 8 - ∣ 5 k - 3 ∣ = - 20

∣ 3 x - 1 ∣ = 5 x
