My homework is asking me to "Solve each system by using multipilicitive inverses of matrices" and I;m guessing the first step is to convert the equations into a matrix, and I don't know how to do that.

My first system to solve is
5x+18y+13
-4x-9y+-5

Please halp me, haha.

If I were a very stupid person, I would just throw the numbers in the matrix and not care where they wound up.

If I were only slightly less stupid, what I do instead? If your brain works like 99.5% of people's, you'll come up with the correct method.

Also, you don't have any equations there O.o

Written in matrix form is:

| 5     18 |              |   13   |
|            |       +      |        |
| -4 -   9 |               |    5   |
