4. 6-3 Elimination Using Addition & Subtraction
Goal:
We will solve equations using addition and subtraction.

5. The variables need to be in the same order on all equations.
You will always have two answers.

6. Example
Solve this system of linear equations by using elimination.
2x + 3y = 11
-2x + 9y = 1

7. Solve this system of linear equations by using elimination.
2x + y = 1
3x - y = 4

8. Solve this system of linear equations by using elimination.
8x + 5y = 38
-8x + 2y = 4

9. Solve this system of linear equations by using elimination.
4x + 6y = 32 and 3x - 6y = 3

10. Solve this system of linear equations by using elimination.
4x + 9y = 24 and 4x - 2y = 2
