Why is this code not running ???

Question

I have tried changing int to float , still no luck :(

Every time i get errors like No Output or Compilation Error !!

i tried these equations :

1) First pair of Equations:

2x + y =5
3x +2y =8

2) Second pair of Equations:

x - 3y - 7 = 0
3x - 3y - 15 = 0

While troubleshooting the code if you get the answers of x and y as :
1) x = 2 , y = 1
2) x = 4 , y = -1
Then, Its correct
