Thanks but can you show me your working for:

(p/4) + (p+1) = 1/3 and "Plug p = -8/15 into (2), and solve for k" I don't understand how you have done these

(p/4) + (p+1) = 1/3

Multiply both sides by 12,

3p+12p+12 = 4 => 15p = -8 => p = -8/15

------

(p/4)(p+1) = k/3 => k = (3/4)p(p+1) = (3/4)(-8/15)(7/15) = -14/75

Thank you
