Question

Medal and Fan! Which product represents the solution to the system?

Answer 1

Do you know how to multiple matrices?

Answer 2

yes, this is my answer

Answer 3

yes that is correct, however, thats a lil complicated how you've done it.

Answer 4

oh wait, you have just used the inverse formula, i see.

Answer 5

i wouldn't leave it in this form , i would simplify this further

Answer 6

because a solution to the system involves values for x and y, here you have just simply solved the inverse.

Answer 7

\[AX=B\]
\[A ^{-1}AX=A ^{-1} B\]
\[IX=A ^{-1}B\]
\[X=A ^{1}B\]

Answer 8

that should be A^(-1) in the last part sorry.

Answer 9

you have solved A^(-1)
