WebBoth were faster than Solve without a domain specification. Solve[eqns, {x, y, z}, Reals] took longer than I was willing to wait, which was much less than the six hours of Bill. We can get the real solution by picking the ones for which {x, y, z} is an element of the Reals. WebI don't need the complex solutions (if exist). only the real solutions. I have posted before a similar question but with 18 equations and it took Maple 40 minutes to solve them. But since then I was able to reduce the number of equations from 18 to 5. This time Maple solved the equations much faster (10 seconds instead of 40 minutes).
