We're modeling a business process and I don't know how to convert this to a
formula:

K=1000
P=6

2*A = (K*P)+(A*P)

I know this is really an algebra question (its been 30 years since I thought
about this stuff), but how do I solve for A?

(In this example A = -1500)

Or, I also know this:

-(2*A)+(K*P)+(A*P)=0


TIA
