52
3(answer)

1. The sum of a number and 17 more than twice the same number is 101 should be:
n + (2n+17) = 101 
Yes, I totally missed some of the wording.
Yes, Quidditch is right for question 1.
Good looking out, Quidditch!

OK, I think you are correct
5  2
=52
=3 
2. I am not sure what
5/2/
means.
If / is supposed to be a bracket or parenthesis then:
5[2]
=5+2 
/ is suppose to be absolute value

The equation is set up correctly. Good job!
Let's see:
17 + 2n = 101....Original Equation
Subtract 17 from both sides.
2n = 101  17
2n = 84
Now divide both sides by the coefficient 2 to find the value of n.
n = 84/2
n = 42
Is this true?
Let's plug 42 for n in the Original Equation above and simplify. If we get the same answer on both sides, then n = 42 is right.
You developed:
17 + 2n = 101....Original Equation
Let n = 42
17 + 2(42) = 101
17 + 84 = 101
101 = 101...It checks!!!
Yes, n = 42.
=========================
NEXT: You are told to evaluate.
To evaluate means to replace the variables given with the given values and simplify.
Evaluate: 5/a+5b if a =12 and
b = 2.
However, I just noticed that you made a typo in terms of 5.
What exactly are you subtracting from 5?
Do you see what I mean?
The second question is not typed correctly.
Write back when you fix the typo. 
Part 1
I don't think you set up the equation correctly. See me first response 
I know that and I thanked you for correcting me.
We all make mistakes, right?
