So, what's all this fuss about
inverse matrices? You
can use them to solve systems of equations.
Check it out:
Let's get that coefficient matrix:
![A = [ row 1: 2 , -5 row 2: 3 , 4 ]](images/07-matrices-03.gif)
Then, we'll need matrices for
![X = [ row 1: x row 2: y ]](images/07-matrices-04.gif) |
![B = [ row 1: 8 row 2: -6 ]](images/07-matrices-05.gif) |
|
our variables |
our "= guys" |
In short, this system
can be rewritten as
and we can use
algebra to solve it!
