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

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

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

• The variables all cancel out.

• Both sides are the same

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

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

• The variables are the same w/ different constants.

• The variables are the same w/ same constants.
