In ordinary mathematics, assuming that x = X and that X2 denotes x2 or x-squared, there cannot be a counterexample since the statement is TRUE.
However, there are two assumptions made that could be false and so could give rise to counterexamples.
1. x is not the same as X. If, for example X = 4x then X = -20 so that X2 = 400.
2a. X2 is not X2 but X times 2. In that case X2 = -10.
2b. X2 is x2 modulo 7, for example. Then X2 = 4.

What is the value of the function x2 plus 3 at x equals 5?
f(x) = x2 + 3 ----> f(5) = (5)2 + 3 ----> f(5) = 28
6x -1 equals 29 what is the value of x² plus x?
6x - 1 = 29 => 6x = 30 => x = 5 Then x2 + x = 25 + 5 = 30
