Best ResponseYou've already chosen the best response.0the first line has 1, a, 2, 2 which means \[x+ay+2z=2\] we know \(y=5\) and \(z=2\) so we have \[x+4a+2\times (2)=2\] or \[x+5a4=2\]

Best ResponseYou've already chosen the best response.0AB will not work since we have a 1 by 3 times a 4 by 1 3 is not 4 BA will work since we have a 4 by 1 times 1 by 3 1 is 1 CB will work 2 by 4 times 4 by 1 because 4 is 4
