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

Consider the system of equations x – y = 3 and 2x + y = 6. The second equation above states that 2x + y is equal to 6. So, if you take the first equation (x – y = 3) and add 2x + y to the left side, and add 6 to the right side, you are adding equal quantities to each side.
