OpenStudy (awesomedude2078):

what's the question

OpenStudy (laacmichael):

what is the solution of the matrix equation? [5 3] [x] =[7] [3 2] [y] =[5]

OpenStudy (sapphiremoon):

Oh, man, sorry, can't do matrices yet, lol.

OpenStudy (laacmichael):

It is ok

OpenStudy (welshfella):

hmm.. its been a while

OpenStudy (welshfella):

if i remember correctly its row * column so we have 5x + 3y = 7 3x + 2y = 5

OpenStudy (laacmichael):

yes

OpenStudy (welshfella):

there is another way of solving them however in which you find the inverse of the 2*2 matrix but i cant remember the details.

OpenStudy (laacmichael):

2, -3 -3, 5

OpenStudy (welshfella):

my knowledge about this is very rusty......

OpenStudy (welshfella):

- is that the inverse?

OpenStudy (laacmichael):

Yes... I think
