What is that you're doing? Are you supposed to solve by using some particular method? Are you maybe using Cramer's Rule...?
Thank you!
Hi
I'm having a little problem solving simultaneous equations in matrices.
2b + t = 14
5b + 5t = 40
[2 1] [b] [14]
[5 5] [t] [40]
1
_____
ad-bc
=
1
_____
(2x5) - (1x5) = 5
[5 -1] [14]
[-5 2] [40]
Then how do I go from there to get:
x(b) = 6
y(t) = 2
I just don't know how to do it
