You can put this solution on YOUR website! .
What the number of 10 does in your post in parts (a) and (c) ?
Where is it came from ?
------------------------------
AVOID posting many problems/questions in one post.
POST THEM SEPARATELY, especially if you need detailed explanations/solutions.
One and ONLY ONE problem/question per post.
It is the RULE, the POLICY and the REQUIREMENT of this forum.
It is written in this page
https://www.algebra.com/tutors/students/ask.mpl?action=ask_question&topic=Equations&return_url=http://www.algebra.com/algebra/homework/equations/
from which you post your problems.
It is assumed that you read these rules before posting.
It is also assumed that you do understand what is written in that page and follow the rules.
Those who violate them, work against their own interests.

So P L E A S E post your problems S E P A R A T E L Y (!)

Comment from student: Sorry, the 10 was a typo, I meant to guess, 5 C 3
My response: Do you see, under given circumstances, I better will not touch this problem, at all - SO INACCURATELY it is written.
PLEASE avoid inaccurate writing when posting to this forum.
Respect the tutors and respect yourself.
