| x/5 |=4

\frac{x}{5} = 4

x = - 20 or x = 20

Solution steps

\frac{x}{5} = 4

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

\frac{x}{5} = - 4 or \frac{x}{5} = 4

\frac{x}{5} = - 4 or \frac{x}{5} = 4

x = - 20 or x = 20

∣ 9 - 12 x ∣ = 45

x^{2} + 2 x - 10 = ∣ x + 2 ∣ + 6

∣ r - 80 ∣ = 1

∣ z ∣ = a

∣ z + 3 ∣ = 5
