You can put this solution on YOUR website! x+y=17 or x=17-y
3y-x=x+2y-13 replace x by (17-y) in this equation & solve for y.
3y-(17-y)=(17-y)+2y-13
3y-17+y=17-y+2y-13
3y+y+y-2y=17-13+17
3y=21 ans.
y+21/3
y=7 ans.
3*7-x=x+2*7-13
21-x-x=14-13
-2x=1-21
-2x=-20
x=-20/-2
x=10 ans.
Proof:
3*7-10=10+2*7-13
21-10=10+14-13
11=11
