-3|2n+4|+5=-13

- 3 ∣ 2 n + 4 ∣ + 5 = - 13

n = - 5 or n = 1

Solution steps

- 3 ∣ 2 n + 4 ∣ + 5 = - 13

Move

5

to the right side

- 3 ∣ 2 n + 4 ∣ = - 18

Divide both sides by

- 3

∣ 2 n + 4 ∣ = 6

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 n + 4 = - 6 or 2 n + 4 = 6

2 n + 4 = - 6 or 2 n + 4 = 6

n = - 5 or n = 1

x^{2} - 3 x - 1 = 2 - x

3 ∣ x - 3 ∣ + 10 = 13

∣ f ∣ - \frac{2}{3} = \frac{5}{6}

∣ 3 x - 2 ∣ = x - 6

x^{2} - 6 = ∣ 5 x ∣
