Question

x + 2 = x + 4 how many ways can you solve this

Answer 1

there is no solution for x. As if we simply the equation we get 2=4 which is never possible.
so the answer is there exists no value of x for which the above condition hold true

Answer 2

Hey dude ... x is not having any value here ... Becoz if we simplify this expression the ans will come as 2=4 so the ans will not come in many ways ...
