2x+3(2x+2/3)=18

2 x + 3 (2 x + \frac{2}{3}) = 18

x = 2

Solution steps

2 x + 3 (2 x + \frac{2}{3}) = 18

Expand

3 (2 x + \frac{2}{3}) : 6 x + 2

2 x + 6 x + 2 = 18

Add similar elements:

2 x + 6 x = 8 x

8 x + 2 = 18

Move

2

to the right side

8 x = 16

Divide both sides by

8

x = 2

20 - 3 (2 + t) = 2 t + 4

x^{2} - 2 x + 65 = 0

3 x^{2} - 10 x - 2 = 0

- 6 (- n - 5) = - 3 (- 4 + 4 n)

(x + 1) (x + 2) = - 3 x - 3
