Hi, I keep running into a road block which I think means either I'm missing something simple, or I'm thinking about things the wrong way. I'm fairly new to sage, and CAS in general, so either is possible.
Here's a simple example of what I'm doing. Lets give ourselves two symbolic equations: sage: var("a b c d e") sage: e1 = a == b + c sage: e2 = d == e * a Now, lets say I want to know what c is in terms of b, d & e. By hand I'd substitute e1 in e2, and then solve for c. sage: e3=e2.subs(a=b+c) sage: solve(e3, c) [c == (d - b*e)/e] All fine, but note that I had to enter e1 into the substitution explicitly. I've yet to find a way of substituting one symbolic equation into another. Is there a way? Where am I going wrong?
