Answer:
29 and 35
Step-by-step explanation:
x+y=64
x-y=6
Solve by substitution. 
x=6+y
6+y+y=64
6+2y=64
y=29
Then plug in 29 for y. 
x+29=64 ......35

Hello from MrBillDoesMath!
Answer:
I think your formula  (2y/x2) is equivalent to
(2*y)/(x^2)      where x^2 means x-squared.
If so, then
(2*y)/(x^2) = (2*3)/(4*4) = 6/16 = 3/8
Thank you,
MrB
