Section 4.12:  Solving Systems: Elimination

Ground Rules: If x = 3 and y = 8, what does x + y equal?

Key Idea: We can add equations together and the result is still valid.

Solving Systems with Elimination uses this idea!

Solve the system:  6y ‐ 4x = 34x + 2y = 1

Elimination Ex. #1:

Elimination Ex. #2:

Solve the system:  x + y = 10x ‐ y = 3

Elimination Ex. #3: Solve the system:  3x + 2y = 113x ‐ 5y = 25
