You don't even need that. Just specify that you want to solve for x and y :
sage: var("x,y,a,b")
(x, y, a, b)

There are people (I, for instance) who hate the guts of
ask.sagemath.org. Seriously, I find the whole system of badges and tags
and colourful symbols and embedded editors both distracting and
discouraging. I
One line answer :
a,b,x,y = var('a,b,x,y') ; solve([ x + y == a, x - 2*y == b
],x,y,dontsolve='a,b')
First statement is to declare symbolic vars a,b,x,y and second statement is
for solving in symbolics x,y
