Re-arranging a formula to find Vm

[Sparkyian]

Can anyone explain to me how to re-arrange the following formula to find V(m).

V(L)=V(m)-(V(m)/2fCR).

Please explain step by step as I am really stuck.

Thank you.

It's just algebra. Start by multiplying both sides by 2fCR in order to get rid of the fraction. Then isolate Vm by putting all of the terms with Vm on one side, and all of the terms without Vm on the other side. Continue collecting terms and stuff until you're left with something of the form

Vm = blah.
