3x+4(-2x+3)=27

3 x + 4 (- 2 x + 3) = 27

x = - 3

Solution steps

3 x + 4 (- 2 x + 3) = 27

Expand

4 (- 2 x + 3) : - 8 x + 12

3 x - 8 x + 12 = 27

Add similar elements:

3 x - 8 x = - 5 x

- 5 x + 12 = 27

Move

12

to the right side

- 5 x = 15

Divide both sides by

- 5

x = - 3

x^{2} - 11 x - 12

36 x^{2} = 49

\frac{5}{∣ x + 6 ∣} \geq 4

3 x + 6 < 21

5 (u + 2) + u = 3 (u - 1) + 1
