**Damon**, Saturday, December 1, 2012 at 7:32pmdivide the second equation by 2

and the two equations are

4x^2 − 27y^3 = 35

4x^2 + 27y^3 = 37

--------------------- add

8 x^2 = 72

x^2 = 9

x = +/- 3

if x = + 3

36 -27 y^3 =35

-27 y^3 = -1

y^3 = 1/27

y = 1/3

so (3,1/3) would be a solution

same solution for y
