2)
Let's solve equation 2) for p and see if it matches equation 1).
2)
Multiply both sides of the equation by (p+1).
2a)
Apply the distributive property to the right side.
2b)
Subtract rp from both sides.
2c)
Simplify this by factoring out the p on the left side.
2d)
Now divide both sides by (1-r).
2e)
You can rewite this as:
2f)
Now compare this with equation 1)
1)
You can see that equation 2f) is the negative reciprocal of equation 1) so Peter is incorrect in his statement.
