Use the Gaussian elimination method to solve the following system of linear equations:

First express the equations in an augmented matrix:

Then apply row operations to convert the coefficient matrix on the left to an identity matrix. The easiest way to do this is to convert the a11 element to 1 and clear column 1, then convert the a22 element to 1 and clear column 2, and so forth, as follows:
