How do you solve #((4, 8), (2, 5))((x), (y))=((0),(6))#?
The general form for inverse of matris
Hence inverse of
Solving (A) by simple matrix multiplication gives us
(this is just an alternative method to that provided by Shwetank Mauria that doesn't require the use of an inverse matrix)
is equivalent to
If we multiply equation  by
and from this
