pf respostae calculo :)

Answer 1

(3x+5)/4-(2x-3)/3=3 (mmc deu 12)
(9x+15)/12-(8x-12)/12=36/12 (corta o 12)
9x+15-8x+12=36
9x-8x=36-15-12
x=9

Prontinho :D

Answer 2

 3x+5  -   2x-3   = 3 -----mmc(3,4) = 12
   4            3
 3(3x+5) - 4(2x-3) = 3 .12
 9x + 15 - 8x + 12 = 36
                          x = 36 - 27
                          x = 9
