-6x - 24y = -63

 6x -   4y = 14           add the equations  giving us

 

- 28x =  - 49        divide both sides by - 28

 

x = 49 / 28 =   7/2      sub this into either equation to find y

 

6(7/2) - 4y  = 14

 

21 - 4y  = 14

 

-4y  = 14 - 21

 

-4y  = - 7       divide by - 4

 

 y =  7/4

 

 

cool cool cool
