Presentation Transcript

1. 7.3 Solving Systems of Equations by Elimination Using Multiplication 1 Solve by Elimination 2 Example Problems 3 Practice Problems

2. Multiply, Then Use Elimination • If the coefficients of either variable in the first equation DO NOT match the corresponding coefficients in the second equation: • Multiply one equation by a number that will make one of the coefficients of a variable match in both equations • Follow the elimination steps

3. Multiply, Then Use Elimination Example

4. Multiply, Then Use Elimination Example (Cont.)

5. Another Example • An untrue solution identifies and Inconsistent System • That means the lines won’t cross… 

6. Practice Problems • Page 391 Problems 13-39 (odd)
