I have two equations that I need to combine to find the value of a variable. My tutor has been through this but I don't get it. Please could you walk me through the steps?
I have 1)Vr = Vm/FCR and 2)VL = Vm-Vr/2 and I need to solve for Vm by substituting equation 1 into equation 2.
The answer I have is Vm=VL/(1-(1/ 2FCR) but I want to know how to get there.
Thanks for your time
