Elimination Method. We will add or subtract our equation together to eliminate one variable. Why is this legal? Solve for the remaining variable. Using the value you found, plug into an equation and find the other variable. Ex. Using the Elimination Method. Solve the system using the elimination method. x + 2y = 10. x + y = 6. 2x + 3y = 12. 5x ...

The rationale is to show the students that for some questions, the elimination method can be quite tedious. Hence they will be able to better appreciate the substitution method when it is shown to them. 5 Consolidation. Refer students back to Worksheet 1 and get them to solve questions 2 – 4 using either of the 2 methods they have just learnt.

19. Solve each of the following systems by elimination. Check your answers by graphing, and paste a screen shot of each graph with the solution shown. a. 3x – 12y = 25 b. .5x = .25y . 2x – 4y = 7 x + 2y = 30. 20. Systems in three variables can also be solved by using the elimination method. Work with any two equations at a time.

The other steps of forward elimination are the same as the Naïve Gauss elimination method. The back substitution steps stay exactly the same as the Naïve Gauss elimination method. Example 4. In the previous two examples, we used Naïve Gauss elimination to solve. using five and six significant digits with chopping in the calculations.
