3. 5.3 Solving Systems of Linear Equations by Elimination
Essential Question: How do you solve systems of linear equations by elimination?
I would like to do the journal packet activity with the tearing of the triangle angles (Activity 1) but with the 3.1 review activity and tearing out the journal pages I don’t think that there is going to be enough time.

4. Vocabulary Review
A system of equations is a set of two or more linear equations
that contain two or more variables.
A solution of a system of equations is an ordered pair that is a
solution of all of the equations.
It is where the equations intersect on the graph.

5. Steps Line up variables and constants
One variable must have opposite coefficient
Add to cancel out one variable
Solve for the variable left over
Substitute answer in for the same variable in one of the original equations
Solve for the other variable
Check the solution

6. Example 1
Solve the system of linear equations by elimination 𝟐𝒙−𝟐𝒚=𝟏𝟎 𝟒𝒙+𝟐𝒚=𝟖

7. Example 2
Solve the system of linear equations by elimination −𝒙+𝟑𝒚=𝟒 𝒙+𝟑𝒚=𝟐

8. Example 3
Solve the system of linear equations by elimination −𝟓𝒙+𝟐𝒚=𝟏𝟑 𝒚+𝟓𝒙=−𝟏
