Ok, easy peasy. This is asking for p as the subject, so we want it to look like p=blah blah blah, just like a normal function with y=x+1 or something. To do this, we want to collect all of our p's together, so lets subtract px from both sides with ap-px=px+c-px which simplifies to ap-px=c. Then we are going to factor out the p to get p(a-x)=c, and then we can divide everything by a-x to finally get p=c/(a-x)

Answer 2

So basically find what p is.

ap=px+c

Move px over:

Ap-px=c

Take p out of both ap and -px:

P(a-x)=c

Divide a-x from both sides:

P=c/(a-x)

Hope this helped :)

Answer 3

ap=px+c

ap-px=c

p(a-x) = c

p = c/(a-x)

Answer 4

Divide both sides by a
