Solution Summary

We discuss the merits of the algebraic and graphical methods for solving systems of simultaneous linear equations and illustrate with an example.

Solution Preview

There is a big difference. Algebraic methods are much more powerful in general. Whereas graphical methods can only be used to solve systems of linear equations involving up to 3 variables, algebraic methods can be used with an arbitrary number of variables. Also, graphical methods in general only yield an approximate ...
