(please write a better title)
Some trivial substitutions are not done by solve:
{{{
sage: x,y=var('x,y')
sage: solve([y==exp(x),2*y-exp(x)==1],x,y)
[y == e^x, 2*y - e^x == 1]
}}}
and, as reported in http://ask.sagemath.org/question/23652/solve-
equations-with-sinx/
{{{
sage: solve([y==sin(x),y+4*sin(x)==5],x,y)
[y == sin(x), y + 4*sin(x) == 5]
}}}
