There is no numerical method that is guaranteed to find every solution of a non polynomial equation, so I don't consider this to be a bug. Sometimes root finding requires a help (look for a solution in 0.1 to 10): (%i2) find_root(5x=5*exp(x),x,0.1,10); (%o2) 4.965114231744276  You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=2671564&group_id=4933
