We're are given the following system of linear equations:


What we'll do, is substitute the

in the second equation by the definition of

given in the first equation (

):

We solve for

from the previous equation:


Now we know

.
In order to get the numerical value of

we use the fact that

in the first equation:

So

.
The answer is n=-2 and m=3.
