From this thread:
Simply brilliant! You have done these type problems before, haven't you? When I grow up I want to be like you.Would be less likely to trip yourself up if you went at it a bit this way:
1: rearrange so less confusing:
-2(xy - y) - x(3 + y) + x + 4xy
2: do 1st term:
-2xy + 2y
3: do 2nd term:
-3x - xy
4: put 'em all together:
-2xy + 2y - 3x - xy + x + 4xy
5: perform conclusion!
