You can put this solution on YOUR website! Remember PEMDAS- it's the order in which you do things in a problem:
Parentheses
Exponents
Multiply
Divide
Addition
Subtraction
In this case, since you have variables, you can't do what's in the parentheses first (n-5) so start with the multiplication.
Multiply 2 out to everything in the parentheses ( 2(n-5) is really 2(n)-2(5))
2(n-5)+n
2(n)-2(5)+n
2n-10+n
combine all the like statements (2n+n)
the final answer is 3n-10
