Asked by Cherie
The total length of the walking path is 8x+xy+6y. Find missing side length. Other side lengths are:
2x-xy+3y
3x-2xy+3y
2x+5xy-y
I know to subtract but I think I’m still doing it wrong. I got two different answers. I got x-xy+y and I got x+3xy+11y. I’m not sure where my mistake is . Please help

the sum of the three given sides is ... 7x + 2xy + 5y
subtract from the total length to find the missing side
your 1st answer seems correct
... how did you get the 2nd one?
