(|n|)/3+5=8

\frac{∣ n ∣}{3} + 5 = 8

n = - 9 or n = 9

Solution steps

\frac{∣ n ∣}{3} + 5 = 8

Move

5

to the right side

\frac{∣ n ∣}{3} = 3

Multiply both sides by

3

∣ n ∣ = 9

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

n = - 9 or n = 9

∣ u ∣ - 13 = - 7

∣ x ∣ + 4 = 7

∣ x - 0.15 ∣ = 5

∣ 8 x + 5 ∣ = 6

1 - x^{2} = 0
