There are several ways to solve the systems of equations algebraically, which will be covered in the lecture. For example, to solve by substitution, you need to solve one equation for one variable and then substitute that expression in the other equation. Sometimes, solving by elimination is the most suitable way, however there are times when using multiplication is needed to get the system ready for elimination. Thus, systems of equations can have an infinite number of solutions, exactly one solution or no solution at all. You'll see the different cases in the lecture.
*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.
