How do you work out y+y in algebra

Y+y = 2y there is no other solution.

1. You have the following function that is shown in the problem above:

f(x)=(x+3)/30 

 2. Then, the domain of the function f(x)=(x+3)/30 is:

 All the real numbers (R)

 3. Therefore, the correct answer for the exercise is the first option (Option A), which is:

 A. x is the set of all real numbers.
