Algebra 2
3.2 Practice with Substitution and Elimination
Solve each system by substitution.
1. y = x + 1
2x + y = 7
2. x = y - 2
3x – y = 6
3. y = 2x + 3
5x – y = -3
4. 6x – 3y = -33
2x + y = - 1
Solve each system by elimination.
5. x + y = 10
x–y=2
6. 4x – 3y = -2
4x + 5y = 14
7. x + 2y = 10
3x – y = 9
8. 2x – 5y = 11
4x + 10y = 18

3.2 Practice with Substitution and Elimination
Solve each system. (You decide which method you want to use.)
9. y = x + 3
5x + y = 9
10. 5x + 4y = 2
-5x – 2y = 4
11. x + 5y = 1
2x = 2 – 10y
12. 2y = -4x
4x + 2y = -11
13. 14x + 2y = 10
x – 5y = 11
14. 4x + 3y = -6
5x – 6y = -27
