Solve the system of 2 equations:

[tex](y - 1)(xy - 2x + y - 1) = 4x^{2} + 4x + 2[/tex]
[tex]y + 3x = 4(x + 1)^{3}[/tex]

Find [tex]x,y \in R[/tex]

x=1 y=i-2

It is also important to write the solution and not to provide answers only.
How can we be sure that the system has no other answers except x=1, y=i-2?
