7(y+3)=5y+8 is this a. solution b. no solution c. infinite solution

First, let's use the Distributive Property to make our equation easier to solve. Remember that the Distributive Property says the following:

Using this, we can multiply the 7 out to the and 3. This gives us:

Now, let's solve for :

We can see that there is one solution for this equation because is equal to one definite value after solving. Thus, our answer is A, one solution.
