subtracted by

----------------- Subtract
-3x = -219

381 is not right, and both sides are negative.
x = 73
============
You were doing the right thing, but you made some mistakes.
------------
y = 219
==================
and i got and got x=127 and to fined y i got and i got they y= 65 and to check it i got
==================
---------------
n = # of $1 bags
f = # of $4 bags
-----
n + f = 282
n + 4f = 501
--------------- subtract
-3f = -219
f = 73 bags at $4
n = 219 bags at $1
