Solving Systems of Equations Review
In your own words, explain the three ways to solve systems of
equations. Under each technique, describe the pros and cons of
solving that way.
Graphing
Substitution
Elimination

2. Checkpoint Quiz 7.1-7.3
Solve each system by graphing.
1. y = –x +2
y = x –4
2. 3x +2y = –8
2x –3y = –1
1
−
3. y = 4 x –1
3
y= 4x+3
Solve each system by substitution.
4. y = 2x –9 5. y = 3x 6. 3x +4y = –7

3. x +3y = 8 y = –x +4 2y –x = –1
1 3
7. x = 2y +2 8. x +3y = 9 9. 2 x + 4 y = 2
3 13
2x + 3y = 11 y=–2x+ 2 x +3y = 7
Solve each system by elimination.
10. 4x + 3y = 24
4x – 3y = –24

4. 11. 2x + y =4
2x + 3y =0
12. x +2y = –7
3x –4y = –1
