Evaluate

a+b/9=

A=51 and B=3

Would I substitute a and B to be 54 so is the answer 6?

Your problem would be more specific if it looked like this:

(a + b)/9 =

Yes, the answer is 6.

Ok thank you I try to put an answer to to see if I am right is that ok?

Parentheses aren't necessary as long as you remember PEMDAS.

You're welcome.

What is that? PEMDAS?
