Using the Elimination Method. Solve the system using the elimination method. x + 2y = 10. x + y = 6. 2x + 3y = 12. 5x – 2y = 11 *Weird situations when solving algebraically… If all your variables cancel out and you get a true equation. Ex. 3 =3 . Then your system is Consistent Dependent. What does that mean? If all your variables cancel out and you get a false equation. Ex. 0 = 19. Then ...

Elimination Method Notes - Solve Linear Equations With Two Varia…
To solve a system of linear equations by elimination requires one of the variables, in both equations, to have opposite numerical coefficients. This can be achieved by multiplying one or both of the equations by an appropriate value. When this is done, the equations are then combined.

We then substitute 3 for y in the other equation and solve for x as follows: = = = = The solution to the original system of equations is thus the point (-2, 3). In other words, we get x = -2 and y = 3. You can verify that this is indeed a solution by substituting these values into the original equations. Next, let's try a harder system of 2 equations with 2 variables: = = Without using ...

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 ...

Using elimination of unknowns method (above), we: Manipulated the equations to eliminate one unknown. We solved for the other unknown and; We back-substituted it in one of the original equations to solve for other unknowns. So, we will try to expand these steps: elimination and back-substitution to a large number of equations. The first method that will be introduced is the Gauss elimination ...
