Solve the equations 4x - 2y = 8, 2x - y = 3.

The set of
equations 4x - 2y = 8 and 2x - y = 3 has to be solved.

Each of these
equations represents a line in the x-y plane. It is possible to write each of them in the
slope-intercept form, y = m*x + b.

4x - 2y = 8

=> y =
2x - 4

2x - y = 3

=> y = 2x - 3

For
both these equations, the slope is the same. These equations represent parallel lines and lines
that are parallel to each other do not intersect. As a result, the given set of equations does
not have a solution.
