    r=2/3t+v so to solve for T.. first take minus the V on both sides like this v-r=2/3t you following this??

    next because we are solving for T we divide by 2/3 to get T my itself. so we have v-r/2/3=t

    do I need to subtract rt from both sides?

    yes you can do that, but we to collect a like terms first

    Oh! The -14n and the -4n can go together.

    yes, but be careful here what happens with the sign when it crosses the equal? recall + becomes - and - becomes +

    So, 18n+g=rt ?

    so now what do we need to get N standing alone?

    subtract the g on both sides, leaving me with 18n=rt-g

    then divide by 18 to get n=rt-g/18 ?

    Okay, I have another problem that I know how to start off but not finish. ax+z=aw -y +y +y And that gives me ax+z+y=aw And thats where I'm not sure where to go from there...

    what are we solving for or what is the problem asking for?

    whoops. the equation is ax+z=aw-y, solve for a. You add y on both sides giving you ax+z+y=aw. And then I don't know what else to do.

    first let's look at the a terms here? are alike? no, but what we can do is them on side.

    so you can do this ax+z+y=aw take the ax-aw and than take -z-y so you should have the following ax-aw=-z-y

    add the 2 a's to get 2a(wx)=-z-y ?

    I have it 2a(wx)=-z-y ? from this point take the wx and divide by -z-y so therefore you would 2a=-z-y/wx next divide by 2 to get the a alone so you should have A=-z-y/2wx.
