3 ∣ 3 x + 4 ∣ - 7 = 5

x = - \frac{8}{3} or x = 0

Solution steps

3 ∣ 3 x + 4 ∣ - 7 = 5

Move

7

to the right side

3 ∣ 3 x + 4 ∣ = 12

Divide both sides by

3

∣ 3 x + 4 ∣ = 4

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

3 x + 4 = - 4 or 3 x + 4 = 4

3 x + 4 = - 4 or 3 x + 4 = 4

x = - \frac{8}{3} or x = 0

8 = 16 - 8 n

n + 5 mn

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

(2 a - 3)^{3} - 2 a + 3

- 16 t^{2} + 64 t + 80 > 50
