2 VARIABLE EQUATIONS-2

 

 

Solve the following equations:

 

1. 2X + 5Y = 16

     X + 8Y = 26

 

 

 

 

 

 

  

2.  3M + 4N = -3

     -M + 4N = -15

 

 

 

 

  

 

 

 

3.  C + 6D = 7

    -C – 2D = -2

 

 

 

 

 

 

4. 2A + 5B = 20

     6A – 5B = 12

 

 

 

 

 

 

5. 8P + 7Q = 43

    2P – 7 = -Q

 

 

 

 

 

 

6. 4A + 3B = 44

   3A + 3B = 39

 

 

 

 

 

 

7. U + V = 11

   -U + V = 9

 

 

 

 

 

 

 

8. 5X + 10Y = 190

     2X – Y = 11

 

 

 

 

 

9. 8T – 3U = 61

     T – U = 7

 

 

 

 

 

 

10.  6P + 5Q = 39

        2P + 3Q = 17
