Solution for (x^2/121)-(y^2/49)=1 equation: 


x in (-oo:+oo)

(x^2)/121-((y^2)/49) = 1 // - 1

(x^2)/121-((y^2)/49)-1 = 0

1/121*x^2 = -(-1/49*y^2-1) // : 1/121

x^2 = 121*(1-(-1/49*y^2))

x^2 = 121*(1/49*y^2+1) // ^ 1/2

abs(x) = 11*(1/49*y^2+1)^(1/2)

x = 11*(1/49*y^2+1)^(1/2) or x = -(11*(1/49*y^2+1)^(1/2))

x in { 11*(1/49*y^2+1)^(1/2), -(11*(1/49*y^2+1)^(1/2)) }
