In each of the following systems of equations determine whether the system has a unique solution, no solution or infinitely many solutions. In case there is a unique solution, find it:



a1x + b1y + c1 = 0


a2x + b2x + c2 = 0


if infinite solution


, no solution


If unique solution


3x – 5y = 20


6x – 10y = 40



Infinitely many solution
