Show that the function f: N * N - > N * N, f(x,y) = (x+y, 2x-3y) is one-to-one.

Show that the function f: N x N - > N x N, f(x,y) = (x+y, 2x-3y) is one-to-one.

(A function f is said to be one -to -one , or injective , if and only if f ( a) = f ( b ) implies that a = b for all a and b in the domain of f. A function is said to be an injection if it is one-to-one.)
