How can i avoid this error?

that happens 'cause I have 3 different solution for Vv:

> Vv3:=Re(solve(eq1,Vv)[3]);

This is what I ve to solve...It's simple!And it works, but if I write:

>fsolve({2*x + y = 1, x - y  = 2}, {x, y});

Due to a do... for cycle I obtain thes data:

....

I have this commands:

> for i from 1 to 10 do x1:=1*i:  g:= x1*exp (T) -1 : T=fsolve( g,T) : y1=3*T end do;               

If i execute if i=1 the first lines will be:

x1 := 1

g := exp(T) - 1                  

T = 0.

y1 = 3 T

Now my questions are two:
