Mai is given these two systems of linear equations to solve: System 1:
System 2:
5x + y = 13
20x + 4y = 64
5x + y = 13
202 = 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).
