Best ResponseYou've already chosen the best response.0Adding matrixes is just adding component parts; like vectors right? 4 3 + 1 5  = 5 8 right? 1 2 6 6 7 8

Best ResponseYou've already chosen the best response.0Is X supposed to be the same for part a and part b? Or are you to find an X matrix for each on ?

Best ResponseYou've already chosen the best response.0B and C look familiar; like they are .... the same somehow; cant recall how to transform B into C like that.... is it with an inverse matrix?

Best ResponseYou've already chosen the best response.0If we subtract B from C we will see what AX has to look like right?

Best ResponseYou've already chosen the best response.0yeah wich is AX=CB so we multiply with the inverse of A ?

Best ResponseYou've already chosen the best response.0AX = 5 3 * a b = 5a +3c = 2 5b +3d= 4 3 2 c d 3a +2c = 8 3b +2d= 1 right?

Best ResponseYou've already chosen the best response.0And: a b * 5 3 = 5a +b3 = 2 a3 +b2= 4 c d 3 2 c5 +d3 = 8 c3 +d2= 1 if I did it right...

Best ResponseYou've already chosen the best response.0lets see if we can equate these things :) 5a +3c = 5a + 3b 3c  3b = 0  5b + 3d = 3a + 2b 3b + 3d + 3a = 0  3a + 2c = 5c + 3d 3a 3c  3d = 0  3b+2d = 3c + 2d 3b  3c = 0

Best ResponseYou've already chosen the best response.03b + 3d +3a = 3a 3c 3d 3b + 3c + 6d = 0

Best ResponseYou've already chosen the best response.0my internet source is closing; so thats as far as I can get you :/ good luck with it :) Just equate and solve for a solution to the equations and youll be fine... :)
