In a certain clothing store,6 shirts and 3 ties cost $79.50 ,and 3 shirts and 2 ties cost $41. determine the cost of each shirt.
6s +3t = 79.50
3s +2t = 41 we are looking for shirt price so let's eliminate t's multiply second eq by -1.5
-4.5s -3t = -61.5 and add to the first equation
1.5 s = 18
s= $ 12
