Which pairs of the following sets are disjoint ?
= { x 1 x is an odd integer between 6 and 10 )
= {xl x is an integer less than 18 )
= { xl x is a multiple of 3 between 7 and 16 )

The equation represents a line, and so does the equation

This means that every point whose coordinates satisfy either of the two equations lies on that particular line

For example, point belongs to the first line, because , and similarly the point belongs to the second line, because

The solution of a system is a point whose coordinates satisfy both equations. This means, as we just saw, that this point lies on both lines.

So, the solution of a linear system is the point of intersection between the two lines.
