-3|x+3|=-15

- 3 ∣ x + 3 ∣ = - 15

x = - 8 or x = 2

Solution steps

- 3 ∣ x + 3 ∣ = - 15

Divide both sides by

- 3

∣ x + 3 ∣ = 5

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x + 3 = - 5 or x + 3 = 5

x + 3 = - 5 or x + 3 = 5

x = - 8 or x = 2

- 80 x^{2} - 160 x - 75

225 x^{2} - 169 y^{2}

∣ x - 4 ∣ \leq 2

0.4 (x + 2.4) = 2.96

(x + 2) (x - 5) = 2 (x - 5)
