In this final lecture of Systems of Equations and Inequalities, Dr. Eaton covers Solving Systems of Equations in Three Variables. You will learn about the solution set which is known as a triple of values and once again cover potential number of solutions such as one solution, no solution, or infinite solutions. Four video examples at the end make sure you understand everything in the lecture.
Use substitution and elimination to solve a system in three variables.
A system in 3 variables can have a unique solution, infinitely many solutions, or no solution.
