2 VARIABLE EQUATIONS

 

Solve the equations:

1. 3A + B = 15

A + 2B = 10

 

 

 

 

 

 

 

 

 

 

2.  2A + 2B = 18

A + 3B = 17

 

 

 

 

 

 

 

 

3.  B+ 6C = 32

B+ 3C = 17

 

 

 

 

 

 

 

 

4. 5A + 2D = 32

    6A + 6D = 42

 

 

 

 

 

 

 

 

 

 

 

5. 3C + 4U = 33

    6C + 3U = 36

 

 

 

 

 

6. 2N + 3M = 28

    3N + 2M = 27

 

 

 

 

 

 

7. A + 2B = 6.5

    2A + B = 5.5

 

 

 

 

 

 

 

8. 5X + 10Y = 190

     2X – Y = 11

 

 

 

 

 

9. 2P – Q = 19

     P + Q = 26

 

 

 

 

10. A + 5B = 69

       A – B = 9
