x+3y=7
2x+y=5
multiply eq 1 with 2 and eq2 with 1
2x+6y=14
2x+y=5
5y=9
y=9/5
x+3y=7
x+3(9/5)=7
x+27/5=7
x=7-27/5
x=7*5 -27/5
x=35-27/5
x=8/5
x=8/5 ,y=9/5
x/y
8/5 /9/5
8/5×5/9
8/9 is answer obtained
2x+y=5
multiply eq 1 with 2 and eq2 with 1
2x+6y=14
2x+y=5
5y=9
y=9/5

x+3(9/5)=7
x+27/5=7
x=7-27/5
x=7*5 -27/5
x=35-27/5
x=8/5
x=8/5 ,y=9/5
x/y
8/5 /9/5
