There are three kinds of people in the world - those who are good at math and those who aren't.

:laugh2:
 
Solve for x: y = 2x + 3

y - 3 = 2x

(y - 3)/2 = 2x/2

(y - 3)/2 = x

Switch around and you get:

x = (y - 3)/2

...even though it's still the same.

Heh heh...

Solve for q:

r = (s - 1)/(1 + q)

r(1 + q) = (s - 1)/(1 + q)*(1 + q)

r + rq = s - 1

rq = s - r - 1

q = (s - r - 1)/r

Well, let's see if I can convert my answer back to r to check...

q = (s - r - 1)/r

r(q) = (s - r - 1)/r*r

rq = s - r - 1

r + rq = s - 1

r(1 + q) = s - 1

r(1 + q)/(1 + q) = (s - 1)/(1 + q)

r = (s - 1)/(1 + q)

Okay, that's enough. I'm done! :)
