Answer :
5y-11/4+3y-7/2=4y-7/3+y-1
8y-11/4-7/2=5y-7/3-1
3y= -7/3-1+11/4+7/2
3y=(-28-12+33+42)/12
y=35/12*1/3
y=35/36
check: 35/36*5-11/4+3*35/36-7/2=4*35/36-7/3+35/36-1
175/36-11/4+105/36-7/2=35/9+35/36-1-7/3
280/36-25/4=(35+140-36-84)/36
55/36=55/36
therefore, L.H.S=R.H.S
8y-11/4-7/2=5y-7/3-1
3y= -7/3-1+11/4+7/2
3y=(-28-12+33+42)/12
y=35/12*1/3
y=35/36
check: 35/36*5-11/4+3*35/36-7/2=4*35/36-7/3+35/36-1
175/36-11/4+105/36-7/2=35/9+35/36-1-7/3
280/36-25/4=(35+140-36-84)/36
55/36=55/36
therefore, L.H.S=R.H.S
