How do you know when it is "no solution"?

• The constants (numbers) are different on either side of the equal sign.

• The constants (numbers) are the same on either side of the equal sign.

• There are no variables

• There are multiple variables (x's)

So how do you know when it is "infinitely many" solutions?

• The constants (numbers) are the same on both sides of the equal sign.

• The constants (numbers) are the different on both sides of the equal sign.

• The answer I solved for is always right.

• Too many numbers that I can't solve
