We will rewrite the equations as a matrix.
==> 1 -2 -3 : -1
2 1 1 : 6
1 3 -2 : 13
Now we need to transform the matrix into the form:
1 0 0 : a
0 1 0 : b
0 0 1 : C
Such that (a, b, c) is the solution to the system.
We will use the elimination method to solve.
First we will multiply R1 by 2 and subtract from R2
==> 1 -2 -3 : -1
0 -5 -7 : -8
