For a twovariable system of equations, there are three types of solutions: no solution, one solution, and infinitely many solutions.

For lines which do not intersect, there is no solution.
 For lines with one point of intersection, there is one solution, which is the point of intersection.
 For lines which lie on top of each other, every point on the lines is a solution; there are infinitely many solutions.
Graph each line.
The first line has a
yintercept of (0, 3.5) and a slope of 0.5.
The second line has a
yintercept of (0, 0.5) and a slope of 0.5.
The solutions to a system of linear equations correspond to the points of intersection of their graphs.
The two lines on this graph intersect at the point (3, 2).
So, the solution to the system of equations is (3, 2), or x = 3 and y = 2.
