Sometimes we will have more than one equation for a problem.
For example,
X equals 2y plus 1
X plus y equals 4
This is called a system of 2 linear equations.
We can find a single pair of values for x and y such that BOTH these equations are satisfied.
That is precisely what is required when we are asked to SOLVE for a system of linear equations. We must find a pair that satisfies ALL the equations in the system simultaneously.
Now how do we go about finding the solution for the system of linear equations?
There are 3 main methods:
