Solving Systems of Inequalities by Graphing

What is the main difference between systems of inequalities and systems of equations?

• Systems of equations have no solutions.

• Systems of equations have multiple solutions.

• Systems of inequalities have multiple solutions.

• Systems of inequalities have one solution.
