8-|3x+6|=5

8 - ∣ 3 x + 6 ∣ = 5

x = - 3 or x = - 1

Solution steps

8 - ∣ 3 x + 6 ∣ = 5

Move

8

to the right side

- ∣ 3 x + 6 ∣ = - 3

Divide both sides by

- 1

∣ 3 x + 6 ∣ = 3

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

3 x + 6 = - 3 or 3 x + 6 = 3

3 x + 6 = - 3 or 3 x + 6 = 3

x = - 3 or x = - 1

- x^{5} + 6 x^{3} - 9 x

- n^{2} - 5 n + 14

(- \frac{3}{2})^{2} + 4 (- \frac{3}{2})

3 x + 30 = 0

3 x - 9 = 5
