(7xy-3x-4y+6)-(10xy+10x-10y+4)

Your answer

$(7xy-3x-4y+6)-(10xy+10x-10y+4) \\ \text{Ok, lets re-arrange this so it is all in one nice long line.} \\ \text{To do this, multiply everything inside the bracket by -1 } \\ \text{as this is what the -ve is doing outside the bracket.} \\ \text{This then becomes} \\ 7xy-3x-4y+6-10xy-10x+10y-4 \\ \text{which simplifies to} -3xy-13x+6y+2 \\ \text{As this is not equal to anything, this is the furthest you} \\ \text{can go with this, so it cannot be solved, but it has been} \\ \text{rearranged and simplified.} \\ $$(7xy-3x-4y+6)-(10xy+10x-10y+4) =6y-3xy-13x+2 $$$ GeordieJake :)
