mmc (4,6,2) = 12

12:4.7x + 12:6.x = 12:2.11x - 12:1.5

3.7x + 2x = 6.11x - 12.5

21x + 2x = 66x = 60

21x + 2x - 66x = 60

23x - 66x = 60

-43x = 60 .(-1)

43x = -60

x = -60/43

7x/4+x/6=11x/2-5

7x/4+x/6-11x/2=-5

mmc(2,4,6)=12

12.7x/4+12x/6-132x/2=-60

21x+2x-66x=-60

-43x=-60

43x=60

x=60/43

21x+2x=66x-60

23x-66x=-60

-43x=-60

43x=60

x=60/43

7x/4 + X/6 = 11x/2 - 5

multiplica por 12

21x+2x= 66x - 60

23x = 66x -60

60 = 43x

x = 60/43
