X2+y2=65............1
X2-3y=37..............2
÷both equation. 1 by 2
X+y=32,5
X=32,5-y......... 3
Sub 3 in 2
(32,5-y)2-3y=37
65-2y-3y=37
65-5y=37
-5y=37-65
-5y= - 28 divide both sides by - 5
Y=5,6........ 4

Sub 4 in 3
x=32,5-y
=32,5-5,6
=26,9

Hope it's the way you wanted it

Westkost [7]
All factors of 12 are {-12, -6, -4, -3, -2, -1, 1, 2, 3, 4, 6, 12}, so x is one of these numbers.

A) t/x   cannot be 1/12, because 1 is not a prime.  NOT POSSIBLE

B) 1/4 = 3/12 ...... 3 is a prime and 12 is a factor of 12.  POSSIBLE
