This post is a continuation of the previous one (click here) which introduced two methods of solving systems of linear equations. We will apply either of these two methods to show how to use them to solve systems of linear equations.
Example 1:
Example 2:
The methods of elimination of variables and substitution of variables were applied to solve the above examples, respectively. You are encouraged to use the other method to solve each example. Since the solutions are already known, you can confirm your results.
