Hi, and we can guess what you input is, when you give us a single equation of a "system of simultaneous equations". Since my cristall ball is broken With[{bgamma012 = 1, dgamma1 = 1, bgamma01 = 1}, FindRoot[ bgamma012 + dgamma1 + bgamma01 - mgamma01 == 0, {mgamma01, 1}] ] work fine, and I can't see you problem.
