### 7.1 7.3 review (11-12)

1. 1. Name Class Date Solving Systems of Equations ReviewIn your own words, explain the three ways to solve systems ofequations. Under each technique, describe the pros and cons ofsolving that way.GraphingSubstitutionElimination
2. 2. Checkpoint Quiz 7.1-7.3Solve each system by graphing.1. y = –x +2 y = x –42. 3x +2y = –8 2x –3y = –1 1 −3. y = 4 x –1 3 y= 4x+3Solve each system by substitution.4. y = 2x –9 5. y = 3x 6. 3x +4y = –7
3. 3. x +3y = 8 y = –x +4 2y –x = –1 1 37. x = 2y +2 8. x +3y = 9 9. 2 x + 4 y = 2 3 13 2x + 3y = 11 y=–2x+ 2 x +3y = 7Solve each system by elimination.10. 4x + 3y = 24 4x – 3y = –24
4. 4. 11. 2x + y =4 2x + 3y =012. x +2y = –7 3x –4y = –1
