Answer: Subtract 3 from each side
Step-by-step explanation:
The goal of the problem is to isolate 3 on one side by itself. The only thing standing in our way is that pesky three. In order to get rid of it, and make y have the whole left side to themselves, we have to see what is three doing in the equation. Well, it is a positive three and it is being added to y. So, we want to do the opposite of what it is. Since it is a positive three, we are going to subtract three on both sides. It will zero itself out on the left side and move on over to the right side, giving y the entire left side of the equation.
20 would be the correct answer, hope this helps =)
Since you cannot have a negative exponent, you would bring a negative exponent from the numinator into the deniminator in order to make it positive or vice versa.
(2^3)+1
