<h2>
Explanation:</h2>
Here we have the following system of linear equations in two variables:
So if you graph these two equations you will get two lines with different slopes. The question is:
<em>What is the result of subtracting the second equation from the first?</em>
So this can be written mathematically as:
So the result of subtracting the second equation from the first is:
and from this we can calculate y.
