Question

5(x+2)/5-(2x+3)/6=3(x+2)/30

Answer 1

5 (x + 2)/5 - (2x + 3)/6 = 3 (x + 2)/30

6x - (2x + 3) + 6 * 2
-------------------------- = (x + 2)/10
              6

(6x - 2x - 3 + 12)/6 = (x + 2)/10

10 (6x - 2x - 3 + 12) = 6 (x + 2)

60x - 20x - 30 + 120 = 6x + 12

40x + 90 = 6x + 12

40x - 6x = 12 - 90

34x = - 78

x = - 78/34

x  = - 39/17

Solución : 

x = - 39/17
