In Example 2, interchange the two equations and then solve the system with the equations in this

Question:

In Example 2, interchange the two equations and then solve the system with the equations in this order.

Data from Example 2

Solve the following system of equations using Gaussian elimination:

The steps are given below, with the necessary row operations shown in red:

To find the value of x, we substitute y = 6/7 into the first equation: x + 1/2 (6/7) = 2 or x = 11/7. Thus, the solution is x + 11/7, y = 6/7 which checks when substituted into the original equations.
