How can you tell that a system of linear equations will have infinitely many solutions without computation?

1 answer:

3 0

If you can manipulate the two equations so that they have exactly the same coefficients (e. g., 3x + 4y = 8 and 2x + 4y = 8), then you conclude that the two lines coincide (overlap), and that there are thus infinitely many solutions.
