Answer 1

9x+7y=2000, 4x+3y=2000 x=1250,y=-1000

Answer 2

income of ramesh=9x
income of suresh=7x
expenditure of ramesh=4x
expenditure of suresh=3x
so,savings of ramesh=9x-4x=5x
savings of suresh=7x-3x=4x
it is given that each saves rs 2000
so sum of their savings=rs4000
5x+4x=4000
9x=4000
x=4000/9
so income of ramesh=9x=9*4000/9
=rs4000
income of suresh=7x=7*4000/9
=rs3111.11
