I know how to solve to get my delta v, instead i'm trying to solve for ISP or weight (whichever is easier) already knowing my delta v to try and build a rocket around how much thrust I need or if I have my thrust than how much it can weigh.

Before I get yelled at to use search this is not a thread on how to calculate Delta V in KSP. I know how to calculate my Delta V in KSP and it's actually really helping me. However I was wondering if you fine folks could help me with something. If I already know how much Delta V I need is there a way to figure out how much ISP I need or how much fuel in terms of weight I'll need? I was never good at math and could not turn around equations. Basically I want to try and solve for ve (ISP) or ln*mo/m1
