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.1in kindergarten, i was confronted by a hole shaped like a triangle, and 4 blocks oddly shaped blocks. instead of measuring stuff and trying to work out some complicated things ... i just picked up each block till i found the one that fit :)

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

Best ResponseYou've already chosen the best response.0hehhe, yes, because is a 2x2, well, yeah, I gather you'd use that :)

Best ResponseYou've already chosen the best response.0hehe, yes, not sure ... if it'd be .... I guess it depends I mean, off you have to get the discriminant, then 2 more discriminants
