Here is an example of two equations with infinite number of solutions
x+y=4
3x+3y=12
Why infinite? They represent the same line, they share the same set of solutions.
Here is one that has no solutions.
y=3x+5
y=3x+3
Here, the lines are parallel, they have the same slope, but are offset (different intercepts). Therefore they share no common point (solution).
When equations have infinitely many solutions, How would you know this?
also, when working on equations that has no solutions, How would I know this? If posible can you give me examples of each. Thank you
