Question: How can I use the answers of solve in the same names?

Hi my friends,

I want to write a command that applies the solutions of an equation in the same name in a procedure, for example the Maple solves the following equation

> solve({2*v+u=1,v+u=0},{v,u});

And gives this answer

But I want Maple applies these values in the same names, namely u=-1 and v=1 in the next statements. In the other words, I want when I write

> u+v;

 Maple gives 0 to me and not


How can I do that?


Thanks in advance for your helps
