Thread Subject: using solve() with variables from the workspace

Everything I see seems to not use any variables from the
workspace

ie I want to do this

x=5;
solve('y+x=9','y')

I would like to get back y=4

I would like to do this with both double and sym type
variables. Is it possible?

Thanks,

Dave

It seems I was misunderstanding subs() completely - it does
exactly what I was asking

c=2;
temp=solve('x+10=c','x')
subs(temp)
