This has infinitely many solutions. The idea is to solve the equation for one of the variables, say for "y". The solution will be in terms of "x" in this case. Then, if you assign any value to "x", you can calculate the corresponding value for "y".

If x is equal to 5, then x squared plus 25 is equal to 50.
(x+5)(x^2-5x+25)
x(x - 25)(x - 25)
x(x + 2)(x + 3) x = 0, -2, -3
If 40 plus x equals 25 then x is equal to -15.
x + x = 2x. Similarly, x^3 + x^3 = 2(x^3)
(x + y)(x + y)(x + y)
This equation has no meaning. 47 cubed is 103,823, but the rest of the equation is worthless without a value for x and t. At present, X and T do not have values, so you can not evaluate this expression.
My iTouch calculator isn't working, so I will simplify the problem for you: x to the 5th power = -4
(2x + 5)(4x^2 - 10x + 25)
The whole of the Real numbers, or even the whole of the complex plane.
