System 2:
5x + y = 13
20x = 52 – 4y
She analyzed them for a moment, and then-without graphing the equations-said, "I got
it! One of the systems has no solution and the other has infinitely many solutions!" Mai
is right!
Which system has no solution and which one has many solutions? Explain or show how
you know (without graphing the equations).
