Question: Write a formal proof that the following statement is true. For all integers m and n, if m is even and n is odd,

Write a formal proof that the following statement is true. For all integers m and n, if m is even and n is odd, then 3n-n + 2m is even. Make sure to use the formal definitions of even and odd. Do not rely on facts that you might know, such as "the sum of two even numbers is always even", unless you actually use the formal definitions of even and odd to prove those facts. You do not have to provide a know-show table; you should only write a formal proof.
