Good evening sir/madam
I am taking online tutions on topperlearning.
I took a test on Linear Equations. 
The question was:

Three consecutive integers add up to give 30. Linear equation representing this is... .

 3x + 3 = 27

 3x - 3 = 30

 3x = 27

 3x = 30

I chose D option. It displayed it wrong.

If we take the variables as :

(x-1), x, (x+1)      or         (x-2), (x-1), x

My answer could be right. I wanted to know why it displayed it wrong
