∣ 3 n - 5 ∣ - 8 = 12

n = - 5 or n = \frac{25}{3}

Solution steps

∣ 3 n - 5 ∣ - 8 = 12

Move

8

to the right side

∣ 3 n - 5 ∣ = 20

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

3 n - 5 = - 20 or 3 n - 5 = 20

3 n - 5 = - 20 or 3 n - 5 = 20

n = - 5 or n = \frac{25}{3}

2 ∣ 3 x - 7 ∣ + 8 = 18

x^{2} + x - 2 = 0

∣ x + 9 ∣ + 7 = 6

x^{2} + 3 x - 26 = - 5

∣ 13 y + 9 ∣ + 8 = 2
