#27+N#

It's not really a difficult task in resolving Algebraic word problems

You just have to note this following principles..

#"sum of"# is same thing as #+# in Algebra

#"of"# #color(white)# is same thing as #xx# in Algebra

#"is"# #color(white)# is same thing as #=# in Algebra

In this case we have #"the sum of 27 and"#

Note that #-># The sum of, has already given you a clue that it's #+#

Hence The sum of 27 and N means #27 + N#

Hope this is explicit..
