-3|2n-8|=-78

- 3 ∣ 2 n - 8 ∣ = - 78

n = - 9 or n = 17

Solution steps

- 3 ∣ 2 n - 8 ∣ = - 78

Divide both sides by

- 3

∣ 2 n - 8 ∣ = 26

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 n - 8 = - 26 or 2 n - 8 = 26

2 n - 8 = - 26 or 2 n - 8 = 26

n = - 9 or n = 17

n (x) = ∣ - 13 x + 1 ∣ + 2

a = \frac{x + 2}{3}

∣ x - 20 ∣ = x + 2

2 - ∣ 2 x - 5 ∣ = 7

- 6 ∣ v ∣ = 0
