put this solution on YOUR website!The key to this question is to collect liketerms.
Liketerms means same letters combining together (order doesn't matter, ie. 3xy can collect together with yx, but not 5xyz or 8x)
so 3xy collect with + xy => gets you 4xy
8x collect with -7x => gets you x
8 collect with -1 => gets you 7
2y collect with -y => gets you y
3z is alone => remains 3z
5xyz + xyz = 6xyz
so final answer becomes: 4xy + x + 7 + y +3z + 6xyz (order doesn't matter)
ie. you may have x + y + 3z + 4xy + 6xyz + 7..that's also correct
