An equation has ____________ when you simplify and the variable terms on each side are the same, AND the constants are the same.

• one solution

• two solutions

• no solution

• infinite solutions

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

• 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.
