steak,s bacon,b
4s + 3b = $36.43...eqn 1
5s + 2b = $35.93...eqn 2
multiply eqn 1 by 2...
8s + 6b = $72.86...eqn 3
multiply eqn 2 by 3
15s + 6b = $107.79...eqn 4
minus eqn 3 from eqn 4
7s = $34.93
s = $4.99
subst for s = $4.99 in eqn 1
$19.96 - 3b = $36.43
=》3b = $16.47
=》 b = $5.49
answer...
pound of bacon cost $5.49
