You entered:

y*(x)=x+4/x^2

x*y = (x + 4)/(x^2)

x*y = (x + 4)*2/x

x*y = (x + 4)/(x^2)

x*y = x + 4/(x^2)

x*y = x + 4*2/x

x*y = x + 4/(x^2)

x*y = x + 4/(x^2)

Find the derivative

(x^2 + y^2)^2 + 18*(x^2 + y^2) = 8*x^3 - 24*y^2*x + 27

(x^2 + y^2)^2 - 2*(x^2 - y^2) + 1 = (3 / 5)^4

(x^2 + y^2)^2 - 2*(x^2 - y^2) + 1 = (4 / 5)^4

(x^2 + y^2)^2 - 2*(x^2 - y^2) + 1 = (6 / 5)^4

(x^2 + y^2)^2 - 2*(x^2 - y^2) + 1 = (7 / 5)^4

(x^2 + y^2)^2 - 2*(x^2 - y^2) + 1 = (8 / 5)^4

2*y^2*(x^2 + y^2) - 10*y^2*(x + y) - 2*y^2 - 9*x^2 + 90*(x + y) - 144 = 0

(y^2 - x^2)*(x - 1)*(2*x - 3) = 4*(x^2 + y^2 - 2*x)

y^2 = x*(81*x^5 + 396*x^4 + 738*x^3 + 660*x^2 + 269*x + 48)

144*(x^4 + y^4) - 225*(x^2 + y^2) + 350*x^2*y^2 + 81 = 0

(x^2 + y^2)^2 + 8*x*(x^2 + y^2) - 16*y^2 = 0

x + sqrt(1 - y^2) = ln([1 + sqrt(1 - y^2)]/y)/2

x + sqrt(1 - y^2) = 3*ln([1 + sqrt(1 - y^2)]/y)/2

x = abs(ln([1 + sqrt(1 - y^2)]/y) - sqrt(1 - y^2))

(2*x^2 + y^2)^2 - 2*sqrt(2)*x*(2*x^2 - 3*y^2) + 2*(y^2 - x^2) = 0

x^3 + x*y^2 - x^2 + y^2 = y*(x^2 + y^2 - 2*x)

-243 - 216*z - 18*x + 4*y^2 + 25*x^2 + 36*z^2 + 16*x*y = 0

x^2+4*y^2+9*z^2+4*x*y+12*y*z+6*x*z-4*x-8*y-12*z+3=0
