Solving Systems of Linear Equations in Three Variables
Select the second and third equations to eliminate the same z variable (multiply the second equation by (3 and add). You now have two equations in terms of x and y. Use any method to solve this system for x and y (elimination is shown here). Substitute x = 3 and y = 4 into the second original equation and solve for z. 2((3) + 3(4) – z = 4. z = 2

Three by three systems of linear equations are also used to solve real-life problems. The given problem is expressed as a system of linear equations and then solved to determine the value of the variables. Sometimes, the system will consist of three equations but not every equation will have three variables. Example three is one such problem.
