Ashraf,
You should read up on Solve, here is what you want to do
Solve[Y==C+M+v*Y,Y]
the Mathematica response is
{{ Y->(C+M)/(1-v)}}
A couple of things to note:
1) the "equals" in the equation is a double = sign.
2) I wrote v*Y instead of vY as you did. You
could also put a space between the v and Y
instead: v Y
3) the answer is a Rule. You will need to read up on those as well.
Here is one way to use the result:
soln=Solve[Y==C+M+v*Y,Y]
y=Y/.soln[[1]]
you will now have y = (C+M)/(1-v)
Good luck,
Kevin
