Question 752011
We'll call them x and y


{{{y=2x+1}}}

{{{x^2-y^2=176}}}


then




{{{x^2-(2x+1)^2=176}}}

{{{x^2-(4x^2+4x+1)=176}}}

{{{-3x^2-4x-177=0}}}

*[invoke quadratic "x", 3, 4, 177 ]





so we see that no pair of real numbers wtii work but



{{{
(1/3)*(-2 +- i *sqrt(527))
}}}


does work


:)
