Hi,         

Solve the following systems of two linear equations

2x+4y =18

 x+2y =13 Multiplying both sides of second equation by -2



 2x+4y =18

-2x -4y = -26  Adding equations together 

  0 ≠ -26  There is NO solution to this system of equations

Note:  Graph indicates they are parallel lines and do not intersect
