Patrick 60 and Quincy 90
P + 8 = X And. Q  5 = Y
Where P=2Q/3. And X=4Y/5
Substituting gives 2Q/3 + 8. = 4Y/5
Change denominator so it's the same for all ........ (10Q + 120)/15 = 12Y/15
X both sides by 15 and sub Y= Q5........................ 150Q + 1800 = 180 (Q5)
Do some maths here and eventually you'll get..........2700 = 180Q  150Q
Therefore................................................................... Q = 90
and ..............................................................................P = 2x90/3 = 60
