Hey mate thank for the question
Hope it helps
First adding eq 1 and 2
1480x+2310y=5270
2310x+1480y=6100
-------------------------
3790x+3790y=11370
3790(x+y)=11370
x+y=11370/3790
x+y=3-------------(4)
Subtracting eq 1 2
2310x+1480y=6100
1480x+2310y=5270
- - -
----------------------------
830x-830y=830
830(x-y)=830
x-y=1--------------(5)
Adding eq 1 2
x+y=3
x-y=1
--------
2x=4
x=4/2
x=2
Putting the value of x in eq 4
2+y=3
y=3-2
y=1
Hope it helps
