Please help advise if my answer is correct
Is the solution of 25 + n = 30 greater or less than 30? Explain how you know without solving it?
By looking at the equation, I know that the value of the n = would be 5. It is not greater or less. It should be equal.
Please let me hear your expertise advise
Thanks!

I agree too that it is equal. Your answer is good too but i would leave out or change the greater or less then sentence to: The answer would is equal because n=5, because n=5 and when you put 5 in the place of n you get 30. 30 is not more or less then 30 so it must be equal: and also write out all the numbers
