25 is the answer to this question
Answer:
Yes, is a solution of .
Step-by-step explanation:
Given
To prove that is a solution of the given expression
Take Right hand side :
Substitute the value of
Now , we get
-(n-1)+2+2{-(n-2)+2}+2n-9
=-n+1+2+2(-n+4)+2n-9 ( simplified)
=-n-6+8-2n+2n ( simplified )
=
Hence, LHS=RHS
Therefore, is a solution of given expression
