x/4+(3x-2)/2=(x-3)/2
x/4+2(3x-2)/4=2(x-3)/4
x+2(3x-2)=2(x-3)
x+6x-4=2x-6
x+6x-2x=-6+4
5x=-2
x=-2/5

Qualquer duvida só perguntar ;)

X/4 + (3x - 2)/2 = (x - 3)/2
mmc de (4,2,2)
4,2,2/2
2,1,1/2
1,1,1

(2*2) = 4

x + 2.(3x - 2) = 2.(x - 3)
x + 6x - 4 = 2x - 6
6x - 2x + x = - 6 + 4
5x = - 2
x = - 2/ 5
