Solve one function in terms of another

I want to express y(t) in terms of x(t). For example:

syms x(t) y(t) t
eq=x+2*y==10;
solve(eq,y)

The code gives the following error:

Warning: Unable to find explicit solution. For options, see help. Empty sym: 0-by-1

I would like to have this y(t)=(10-x(t))/2 becasuse then i'm going to combine this equation with others that are differential in function of t.

Thanks.

Use isolate instead of solve in this instance —

syms x(t) y(t) t
eq=x+2*y==10;
soln = isolate(eq,y)

soln = 

LHS = lhs(soln)

LHS = 

RHS = rhs(soln)

RHS =
