Math help.. simple hopefully

I am a bit ashamed I cannot remember how to do simple arithmetic but it seems like I'm in the same boat as people around me.

I have this equation:

(P * (.06 / 12)) / 0.164 = 760.55 (rounded up)

I need to figure out what P is (it's 25,000 but I need the steps to get me there) Any help would be appreciated.

(This isn't for school btw just a project at work)

Use Wolfram Alpha next time. :P

If it doesn't explain it enough, what exactly do you mean by steps, because there's honestly not many steps in that to begin with. The inner division first, then the multiplication with P, divided by 0.164, then you divide both sides by whatever P is being multiplied by.

Putting solve in front of the equation will often offer a better breakdown as well:

Wolfram Alpha got me through my differential equations class. It does perfect laplace transforms and shows the steps too.... I about blew my load the first time I saw it. Amazing piece of software.

It looks like you already got your answer with wolfram. If you are looking for a step by step algebraic approach:

(P (.06 / 12)) / 0.164 = 760.55

1) Divide .06 by 12
(P (.005)) / 0.164 = 760.55

2) Multiply both sides of the equation by 0.164 to remove the denominator.
(0.164)(P (.005)) / 0.164 = 760.55 (0.164)

Which is equal to:
(P (.005)) = 124.7302

3) Now divide both sides by .005 to isolate the variable P
(P * (.005)) / .005 = 124.7302 / .005

Which is equal to:
P = 24,946.04 or 25,000 (in significant numbers)

Hope that helps

Math, my boy, is nothing more than...
Code:
if(getThingFlags(source) & 0x8){
  do her}
elseif(getThingFlags(source) & 0x4){
  do other babe}
else{
  do a dude}
