Answer:

<h2><u><em>P = 16</em></u></h2><h2><u><em>C = 24-P = 8</em></u></h2>

Step-by-step explanation:

Heads: P + C = 24

C = 24 - P

Legs: 4P + 2C = 80

Substitute, from heads: 4P + 2 (24 - P) = 80

4P + 48 - 2P = 80

2P = 32

<u><em>P = 16</em></u>

<u><em></em></u>

<u><em>C = 24-P = 8</em></u>

====================

Check:

P + C = 16 + 8 = 24

4P + 2C = 4(16) + 2(8) = 64 + 16 = 80

X/y = 2 so x = 2y
z/x = 4 so z = 4x but x = 2y so z = 4(2y) = 8y

now you have
x = 2y, z = 8y 

x + y + z          2y  + y + 8y             11y              11
------------ = -----------------------= ------------- =   ----------- = 5 1/2
     x                          2y                  2y                  2
