Hello! A newb question I'm sure... :-) Here's a couple of equations: eq1 = n*Sin[x] == (m*v^2)/r; eq2 = n*Cos[x] == m*g; The goal is to solve for 'x'. I can do this in a roundabout way via: Solve[eq1 /. Solve[eq2, n], x] I.e. solve eq2 for 'n', substitute this into eq1, and solve the result for 'x'. But this approach seems too "manual". Is there a more straightforward way to carry out the problem? I tried this: Solve[{eq1, eq2}, x] but it doesn't seem to work. What's a good way to go about this? Thanks! Ed
