Simultaneous equations - introduction

The term simultaneous equations refer to a pair of equations that are solved jointly at the same time. In simultaneous equations, the number of unknown present in the equations usually determine the number of equations to be given. This is because the number of unknown has a direct bearing with the number of equations to the solved.
A pair of simultaneous equations is in the form given below
2x – 2y = 14 and

2x + y = 8.
There are three methods used in solving simultaneous equations. These are
   1.   Elimination method;
   2.   Substitution method, and
   3.   Graphical method.
Note

Only the first two are treated in this blog.
