Use the Gauss-Jordan Elimination method to solve the system, following the steps outlined below.
-21x + 8y = -173
-8x + 3y = -66
-21 8 -173
1.
Convert the system into an augmented
matrix.
-8 3 -66
2.
Use row operations to get a 1 in row 1,
column 1.
3.
Use row operations to get a 0 in row 2,
column 1.
4.
Use row operations to get a 1 in row 2,
column 2.
5.
Use row operations to get a 0 in row 1,
column 2.
The solution to the system is x = and y = .
