The statement "number (a) = number (a)" is an identity, which means it is true for all values of the variable "a." An identity has an infinite number of solutions because no matter what number "a" represents, it will always be equal to itself. Therefore, this problem has infinitely many solutions.
For example, if "a" is 12 (as in your example), the statement becomes 12 = 12, which is true. Similarly, if "a" is -5, the statement becomes -5 = -5, which is also true. The equality holds for any real number (or even complex number) you substitute for "a."
how many solutions this problem have? number (a) = number (a)
ex: 12 = 12
