Best ResponseYou've already chosen the best response.0well, to cancel out the "y" I'd just do 6 * n = 7 n = 7/6 thus 6 * 7/6 = 7 that gives you a 7y at the bottom, thus cancelling out "y"

Best ResponseYou've already chosen the best response.0@jdoe0001 ....one of us is on crack... i have no idea what you are doing. Cramer's Rule is so much more easier
