I figured out the solution by graphing, there is no solution to these set of equations.
This has a nicer solution.
We can make as many solvable systems as we like, by changing the right-hand side of the second and third equations. Pick a number for x (not zero).
x^2 - y^2 = (x^4 - 144)/x^2
7x - 3x = 4x
The solution will be:
x = x (the number you picked)
y = 12/x
