It is impossible to read exactly what the expression is - it looks like there are some operators missing from expression: between the 2 and 5n, between the 5 and n, between the 3 and n.
As written it looks like: 25n + 3 + 5n + 3n + 2 = 33n + 5 which is not divisible by 17 for n = 1 (at least).
Please re-ask your question spelling out every operator, eg 2 bracket 5n plus 3 close bracket plus 3 minus n...

# For every natural number x, x = x. That is, equality is reflexive. # For all natural numbers x and y, if x = y, then y = x. That is, equality is symmetric. # For all natural numbers x, y and z, if x = y and y = z, then x = z. That is, equality is transitive. # For all a and b, if a is a natural number and a = b, then b is also a natural number. That is, the natural numbers are closed under equality. # 0 is a natural number. # For every natural number n, S(n) is a natural number. # For every natural number n, S(n) ≠ 0. That is, there is no natural number whose successor is 0. # For all natural numbers m and n, if S(m) = S(n), then m = n. That is, S is an # If K is a set such that: #* 0 is in K, and #* for every natural number n, if n is in K, then S(n) is in K, then K contains every natural number. # If φ is a unary predicate such that: # #: #:* φ(0) is true, and #: #:* for every natural number n, if φ(n) is true, then φ(S(n)) is true, #: then φ(n) is true for every natural number n. Or. None of the above is relevant as... 1 + 1 = 3

Friends, faulty logic is for fun - nothing serious about it. Yes, it's wrong, however the reason beneath is hidden :) So try and prove that 1divided by 2 is not 0.5. No, because it is, and if they do, there is something wrong with it.
It is REM(4n/6)=4. Prove. Correction.
An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2. 6 is an even number.
Cannot prove that 2 divided by 10 equals 2 because it is not true.
-16 ÷ -2 = (-1)(16)/(-1)(2) = 16/2 = 8
You can usually make valid transformations in one of the expressions until you get the other expression. A "valid transformation" in this context means one that doesn't change the value of the expression.

A variable raised to a power:i.e., X2 is not equal to 2X...you can prove it by substituting a number for X...if you choose X=1, then 12 = 1 & 21 = 2, which are not equal obviously.
To prove whether a number is composite, factor it. A number having any factor besides 1 and itself is composite.
The same reasoning you may have seen in high school to prove that the square root of 2 is not rational can be applied to the square root of any natural number that is not a perfect square.
The sum of an odd and an even number is odd. Any odd number can be expressed as 2n + 1 (for some integer "n"). Any even number can be expressed as 2m (for another integer, "m"). The sum of the two is 2(m+n) + 1. Since the expression in parentheses is an integer, multiplying it by 2 gives you an even number. Adding 1 makes the entire expression odd.
