Hm.  Did you have ideas on how to do this?  That we might try at least.

ashleyisakitty · Answer

Not really, i have the determinants of each matrix but thats it. :/

accessdenied · Answer

I think it will be easier that these matrices are simply equal.  That means the corresponding entries are equal.
[ a   b  ]      [ e   f]
[ c   d  ]  =  [ g  h]
implies that
a=e,   c=g,  b=f,  and d=h.
Because if they were any different, they wouldn't be the same matrix anymore right?

{{-6,9}{7,3}} ?

ashleyisakitty · Answer

excuse me. 

k=-6
w=9
f=7
and then 3.

accessdenied · Answer

2f = -14   <-- negative 14,  so f = -7.  Otherwise, yes, I agree with those answers.  :)
