A) x^2 + y^2 = 37
B) x * y = 24
B) x = 24/y then substituting this into A)

A) (24/y)^2 + y^2 = 37
Multiplying both sides by y^2
A) 24 + y^4 = 37y^2
A) y^4 - 37y^2 +24 = 0
y = 6.028230484554424
x * y = 24
x = 24 / 6.028230484554424
x = <span> <span> <span> 3.9812678134 </span> </span> </span>
There is x and y but I'm not too sure of it.
