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??

2
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

I have one last problem thats bugging me and that is -14n+q=rt-4n, solve for n.

first what do you know already

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.

2
yes, but be careful here what happens with the sign when it crosses the equal? recall + becomes - and - becomes +

So, 18n+g=rt ?
godorovg
Best Response

2
that is correct

2
so now what do we need to get N standing alone?

hint look at the g.
Josizzle98

1
subtract the g on both sides, leaving me with 18n=rt-g
godorovg

2
yes

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?
Josizzle98
Best Response

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.

okay this one is more tricky, but do able

first let's look at the a terms here? are alike? no, but what we can do is them on side.
godorovg
Best Response
You've already chosen the best response.
2
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

got it?

this is where it is tricky what can we do with the a's here?

1
add the 2 a's to get 2a(wx)=-z-y ?
godorovg
Best Response

2
try factoring an a.

2
did you factor an A?

I don't understand again..
godorovg
Best Response
You've already chosen the best response.
2
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.
