Algebra question

    In algebra can you take this:


    [tex] Y = (P)(Q) + (P) [/tex]

    divide both sides by Q and obtain:

    [tex] Y/Q = P + P [/tex]

    or if you divided by Q would you get:

    [tex]Y/Q = P + P/Q[/tex]

    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?

    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 :biggrin:
