In this video lesson you will learn how to solve systems of equations by substitution. By substituting, you can solve systems of equations without the more tedious method of graphing out all the equations. You will also understand the possible number of solutions which range from one to infinite and even no solutions.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
