17x+13y=19 ----- multiply by 17 --- eq 1
13x+17y=41 ----- multiply by 13

289x+221y=323 ------ equation 2
169x+221y=533 ------ equation 3

subtracting eq. 2 from eq 1

120x=-210
x= -210/120
x= -7/4 ------ eq. 4

putting eq 4 in eq 1
17x+13y=19
13y=19+119/4
y=76+119/52
y=195/52
y=15/4

I hope you u will mark me if this is correct!
