The seven equations for solution yielded by these are : 

 51a; +12-5(a + 6 + c + fZ)=:5997 

 51y + 12-5 (ft + 6 + c + d) = 6021 

 51^ + 12-5(a + 6 + c + cZ) = 5948-5 

 38-5a+12-5(a; + 2/ + 2) =4639-5 

 S8-5b + 12-5 (x + y + z) =4478 

 S8-5c + 12-5(x + y + z) =4426-5 

 SS5d+12-5(x + y + z) =4479-5. 



These are all independent and supply definite values of 

 X, y, Zy a, h, c, d.
