ok so I asked a question like this before and I understood how to do it and a cuple more like it but now I don't understand how to do this on .....
I keep on trying to find the answer but I just don't understand what I am supposed to do
-5(2w+1)=25

  • math - ,

    Multiply negative 5 by 2w then you add 1 and see if the answer is right.

    thankyou,
    but I am still confused I need step by step instructions because I don't think I got the right answer

  • math - ,

    The first thing that you to is distribute the -5 to both the terms in parenthesese.
    So you get -10W-5=25.
    than you add five to both sides and get -10w=30.
    The last thing you do is divide both sides by -10.
    w=-3.
