2|v-4|=38

2 ∣ v - 4 ∣ = 38

v = - 15 or v = 23

Solution steps

2 ∣ v - 4 ∣ = 38

Divide both sides by

2

∣ v - 4 ∣ = 19

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

v - 4 = - 19 or v - 4 = 19

v - 4 = - 19 or v - 4 = 19

v = - 15 or v = 23

x^{2} - ∣ 2 x - 3 ∣ - 4 = 0

∣ y + 975 ∣ = 5

∣ c + 9 ∣ - 1 = 68

7 + 9 ∣ 5 k ∣ = 97

5 ∣ y ∣ - 6 = 6
