Question:

Consider the system of equations: 2x + y = 5 and 4x + 2y = 10. How many solutions are there to this system?

Sheena M.

Answer:

There are an infinite number of solutions to this system. If you multiply the first equation by 2 you will see both equations are the same. Because they are the same you will be able to put any x/y combination into the system and come out with the same answer.
