In that equation, you have to add the 5 over to the 3. You do this because you want the variable (x) by itself, meaning on one side. That’s why after you add the 5, you will have to divide by 2 to get x by itself. Hope this helps.
I'd say B. but that's only because I divided the number of times he flipped the coin by the number of sides it has, 2, and came up with 246. The closest number on here to that is 231 or B. I hope I helped.
