to further simplify this expression {2n + 4}/2 , we are going to factorize 2 from the numerator ,
we have
=2(n +2)/2
the next step to simplify the 2(n +2)/2 further is to use the factorised 2 at the numerator to divide the 2 at the denominator so that we can have a simplified expression.
we have
=2(n +2)/2
=n+2
therefore the simplified form of the expression 8n+4-6n/2 is n+2
