Question

Help with matrices?

Answer 1

I'll try and give it a go, what's the problem?

Answer 2

I have a guess... do I have to use division?

Answer 3

nope, for these types of problems, where Ax = B (A and B are matrices),
x = B*A^(-1) (B times the inverse of A)

do you know how to invert a matrix?

Answer 4

OH WAIT HOLD ON

Answer 5

WRONG ORDER, it should be x = A^(-1) * B, the order matters for matrices!

Answer 6

I don't know how to do the inverse...

Answer 7

yes and inverse of a equals adjoint of a divided by determinrnt of a
if ur considering
ax = b
x = a inverse b

Answer 8

But now that I know the formula I can just look up how to do the inverse. thank you
