solving without numbers

[jess110]

I need to solve this equation if i could just get some help on the first few steps please?
P[sub:3p144geh]1[/sub:3p144geh]+xgy[sub:3p144geh]1[/sub:3p144geh]+1/2xv[sub:3p144geh]1[/sub:3p144geh][sup:3p144geh]2[/sup:3p144geh]=P[sub:3p144geh]2[/sub:3p144geh]]+xgy[sub:3p144geh]2[/sub:3p144geh]+1/2xv[sub:3p144geh]2[/sub:3p144geh][sup:3p144geh]2[/sup:3p144geh]

I am needing to solve for
P[sub:3p144geh]1[/sub:3p144geh]
y[sub:3p144geh]1[/sub:3p144geh]
v[sub:3p144geh]1[/sub:3p144geh]
x

really if someone could just help with one I can get the rest :?:

I have tried solving for P[sub:3p144geh]1[/sub:3p144geh]
and this is what I got??? I feel like it's wrong: P[sub:3p144geh]1[/sub:3p144geh]=P[sub:3p144geh]2[/sub:3p144geh]=y[sub:3p144geh]2[/sub:3p144geh]-y[sub:3p144geh]1[/sub:3p144geh]+v[sub:3p144geh]2[/sub:3p144geh][sup:3p144geh]2[/sup:3p144geh]-v[sub:3p144geh]1[/sub:3p144geh][sup:3p144geh]2[/sup:3p144geh]
so I did it again and this?? P[sub:3p144geh]1[/sub:3p144geh]=P[sub:3p144geh]2[/sub:3p144geh]+y[sub:3p144geh]2[/sub:3p144geh]/y[sub:3p144geh]1[/sub:3p144geh]+v[sub:3p144geh]2[/sub:3p144geh][sup:3p144geh]2[/sup:3p144geh]/v[sub:3p144geh]1[/sub:3p144geh][sup:3p144geh]2[/sup:3p144geh]
PLEASE HELP ME
so is the answer simplified to P[sub:3p144geh]1[/sub:3p144geh] going to be P[sub:3p144geh]1[/sub:3p144geh]=P[sub:3p144geh]2[/sub:3p144geh]+y[sub:3p144geh]2[/sub:3p144geh]-y[sub:3p144geh]1[/sub:3p144geh]+v[sub:3p144geh]2[/sub:3p144geh][sup:3p144geh]2[/sup:3p144geh]-v[sub:3p144geh]1[/sub:3p144geh][sup:3p144geh]2[/sup:3p144geh] :?:
are either of these right? that I've listed above?

PLEASE HELP ME

 

[jess110]

so are any of my answers right?
I need steps please I can't really believe I'm not getting this ...grrr...
so how do I simplify then?

Where did the two "1/2" disappear to?

Can you solve this for b:
abc = b + x

 

[jess110]

abc=b+x
/ac=/ac
b=b+x/ac
-b=-b
0=x/ac

b=0 ?

I'm guessing I canceled the 1/2?

Sorry Jess, but you need classroom help; we can't teach here.
