3s + 2p = 85.50....multiply by -1
3s + 4p = 123
--------------------
-3s - 2p = -85.50 (result of multiplying by -1)
3s + 4p = 123
--------------------add
2p = 37.50
p = 37.50/2
p = 18.75 <=== cost of the pants
3s + 4p = 123
3s + 4(18.75) = 123
3s + 75 = 123
3s = 123 - 75
3s = 48
s = 48/3
s = 16 <=== cost of each shirt
