Question

Show graphically that each one of the following systems of equations is in-consistent (i.e., has no solution)

3x -5y =20

6x -10 y =40

Answer 1

Thus we have the following table giving points on the line 3x-5y =20

Thus we have the following table giving points on the line 6x-10y =40

Clearly, there is no common point between these two lines
Hence, given system of equations is in consistent.
