Then P is the number of pig-heads, and 4*P is the number of pigs-feet.
C = number of chickens
Then C is the number of chicken-heads, and 2*C is the number of chicken-feet.
Thus: 21 = P + C
Equivalently: 42 = 2*P + 2*C
Also: 54 = 4*P + 2*C
Thus (54-42) = 4*P + 2*C - 2*P - 2*C
Factoring: 12 = 2*P + ( 2*C - 2*C)
Reducing: 6 = P

Or, do it on graph-paper, with 'P' on the X-axis and 'C' on the Y-axis,
and each unit representing one animal (pig or chicken).
Draw one line between (0,21) and (21,0) (no pigs & 21 chickens, versus 21 pigs & 0 chickens)
Draw one line between (0,27) [no pigs and 27 pairs of chicken-feet]
and (13,1) [13 pigs have 52 feet, with 1 pair of chicken-feet]
The two lines cross at exactly one point on the graph, namely at the solution.
