Question

5x-3/4 -3x+8/2 = 6x-3/3 + x/2 qual o resultado.?

Answer 1

5x/1 - 3/4 - 3x/1 + 8/2 = 6x/1 - 3/3 + x/2
mmc = 12
60x - 9 - 36x + 48 = 72x - 12 + 6x 
60x - 36x - 72x - 6x = -12 + 9 - 48
-54x = -51 
54x = 51
x = 51/54 =17/18 ****

Answer 2

5x-3/4-3x+8/2=6x-3/3+x/2

mmc 

4,2,3,2/2
2,1,3,1/2
1,1,3,1/3
   mmc=  12 

15x-9-18x+48=24x-12+6x

15x-18x-24x-6x=-12+9-48
-33x=-51  (-1) 
33x=51
x=51/33  = 17/11  

Espero ter ajudado!
