| n/(10)|=2

\frac{n}{10} = 2

n = - 20 or n = 20

Solution steps

\frac{n}{10} = 2

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

\frac{n}{10} = - 2 or \frac{n}{10} = 2

\frac{n}{10} = - 2 or \frac{n}{10} = 2

n = - 20 or n = 20

j (x) = - ∣ 4 x ∣ - 1

∣ 9 x - 9 ∣ + 4 = 76

∣ 4 x - 3 ∣ - 4 = 0

4 ∣ 3 x - 2 ∣ = 40

∣ x - 8 ∣ = 0
