Dear all thanks for your previous repoonse. Since I'm very new to Mathematica, I was wondering what Replace[] function means in the following case!! Soln=Solve[MS==P*(K*Y+S*r),r] Z=ReplaceAll[r,Soln[[1]]] I know that first expression yields to r->-(-MS+K P Y)/PS while the second gives -(-MS+K P Y)/PS . But what does Z actually means (i.e replacing r with first part of itself) because if my input is Soln[[1]], I will get r->-(-MS+K P Y)/PS so why when I input Z=ReplaceAll[r,Soln[[1]]] , r-> is eliminated from the output Thanx!!
