the given system of eq. is 23x-29y=98...(i)
29x-23y-110....(ii)
52x-52y=208
52(x-y)=208
x-y208÷52=4
x-y-4
x-y-4.....(iii)
29x-23x-23y+29y=110-98
6x+6y=12
6(x+y)=12
x+y=12÷6=2
x+y=2.............(4)
2x=2+4=6
x=6÷2=3
puttingx=3 in eq.(4)
3+y=2
y=2-3=-1
29x-23y-110....(ii)
52x-52y=208
52(x-y)=208
x-y208÷52=4
x-y-4
x-y-4.....(iii)
29x-23x-23y+29y=110-98
6x+6y=12
6(x+y)=12
x+y=12÷6=2
x+y=2.............(4)
2x=2+4=6
x=6÷2=3
puttingx=3 in eq.(4)
3+y=2
y=2-3=-1
