Original Message (ID '101659') By Bill Simpson:
The reason your Solve is returning {} is In[1]:= Simplify[lengte (1-1/2 u2) u2+offsetgevelxy (-2+u2) u2 (-1+(offsetgevelxy (-2+ u2)+(40-20 u2) v3)/(offsetgevelxy (-2+u2)))] Out[1]= -1/2(-2+u2)u2(lengte+40 v3) In[2]:= Simplify[u2 (lengte (1-1/2 u2)+(40-20 u2) v3)] Out[2]= -1/2(-2+u2)u2(lengte+40 v3) So you are saying Solve[c*v3==c*v3, v3]. Now, if I understand your actual problem, I believe this may help you Solve[{x==f1,x==f2,y==f3,y==f4,z==f5,z==f6},{x,y,z,v2,v3,all,other,variables,in,those,six,functions}] but I cannot be certain when your problem is too complicated to show.
