asking that question is like asking how we know what 2 plus 2 there is no answer
Yes, there is an answer.
To add even numbers is to add sets of two. When you add sets of two, you will always come up with another set of two. Addition of even numbers does not divide the set in two in half, which would result in an odd answer.
In Algebra, ax + bx = (b+c)x. If x is two, then we have the addition of even numbers. The result, we see, is divisible by x-two-and thus be an even number.
