Question

(y-5)/10+(1-2y)/5=(3-4)/4

Answer 1

(y-5)/10+(1-2y)/5=(3-4)/4

tudo vezes 40

4*(y-5)+8*(1-2y)=10*(3-4)

4y-20+8-16y=-10

4y-16y=-10+20-8

-12y=2

y=-2/12

y=-1/6

Answer 2

y/10-5/10+1/5-2y/5=-1/4

y/10-4y/10-5/10+2/10=-1/4

-3y/10-3/10=-1/4

-3y/10=-1/4+3/10

-3y/10=-5/20+6/20

-3y/10=1/20

-3y=10/20

-3y=1/2

y=1/-6=-1/6
