1.  Solve by substitution: 1. y = 2x+3 y = 4x+5 2. A tow company charges $2 per mile plus a fee of $20. Another company charges $5 per mile plus a $10 fee. At how many miles will the two companies cost the same amount? Learning Target: I can solve systems of equations by elimination.

4. 5x – 6y = -32 3x + 6y = 48

5. 6x – 3y = 3 5y + -6x = 3

6. x + y = 10 x – y = 2

7. The sum of two numbers is 82. The difference is 14. What are the two numbers?

9.  Solve by elimination: 1. 2x + 4y = 8 4x – 4y = 4 2. The sum of two numbers is 50. The difference of the two numbers is 6. What are the two numbers? Learning Target: I can solve systems of equations by elimination.

11. 2x+ 5y = -22 10x + 3y = 22

12. -2x + 15y = -32 7x – 5y = 17

13. 2x + 7y = -7 7y + 5x = 14

14. The sum of two numbers is 92, and their difference is 20. What are the numbers?

16.  Solve by elimination: 1. 4x + 2y = 2 5x – 4y = 6 2. The sum of two numbers is 158. The difference of the two numbers is 72. What are the two numbers? Learning Target: I can solve systems of equations by elimination.

18. 4x + 2y = 14 7x – 3y = -8

19. 15x + 3y = 9 -7y – 10x = 4

20. 8x + 3y = -21 4x + 5y = -7
