Question

resolva  (3x - 2)/3 - ( x + 1)/2 = (2x - 5)/5

Answer 1

Vamos lá :

 (3x - 2)/3 - ( x + 1)/2 = (2x - 5)/5

Mmc (3 , 2 , 5) = 30

10(3x - 2) - 15.(x + 1) = 6.(2x - 5)

30x - 20 - 15x - 15 = 12x - 30

30x - 15x - 20 - 15 = 12x - 30

15x - 35 = 12x - 30

15x - 12x = - 30 + 35

3x = 5        ---> x = 5 / 3

Espero ter ajudado !!!
