-|v-4|=-4

- ∣ v - 4 ∣ = - 4

v = 0 or v = 8

Solution steps

- ∣ v - 4 ∣ = - 4

Divide both sides by

- 1

∣ v - 4 ∣ = 4

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

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

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

v = 0 or v = 8

x^{2} - 1 = 1 - x^{2}

∣ - 3 z - 8 ∣ + 7 = 7

x^{2} - 24 = - 2 x

x^{2} - 2 x - 1 = 1

∣ x ∣ = 25.1
