# Algebra question

In algebra can you take this:

$$Y = (P)(Q) + (P)$$

divide both sides by Q and obtain:

$$Y/Q = P + P$$

or if you divided by Q would you get:

$$Y/Q = P + P/Q$$

Thankyou vm

So what is a trick to get the Y and the Q on the left side with out leaving any Q on the right?
Factor out the P's and then divide by q?

Yup, thats correct (if you're talking about the first equation, that is)

Given y = pq + p, you factor out the p and divide both sides by q+1.

Thanks for the correction-- in my head I took that as reading q+1 and assumed it was correct. Sorry, I should pay more attention
