Answer:
   (x, y) = (77/240, -3/10)
Step-by-step explanation:
It is convenient to write the equations in standard form.
Multiplying the first equation by 21 gives ...
   21y = 24x -14
Multiplying the second equation by 8 gives ...
   24x +9y = 5
Then the system of equations in standard form is ...
Subtracting the first from the second, we get ...
   (24x +9y) -(24x -21y) = (5) -(14)
   30y = -9
   y = -9/30 = -3/10
Substituting this into the second equation, we have ...
   24x +9(-3/10) = 5
   24x = 7.7 . . . . . . . add 27/10
   x = 7.7/24 = 77/240
The solution is (x, y) = (77/240, -3/10).
 
        
             
        
        
        
(8)(2)+4(8)(-5)(2)(2) 
The answer is -624
