Question

Find the values of the variables. Matrices help. :~)

Answer 1

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

Answer 2

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

Answer 3

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?

Answer 4

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

Answer 5

excuse me.

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

Answer 6

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

Answer 7

thanks a lot AD :~D

Answer 8

Glad to help! :)
