In a certain clothing store, 3 shirts and 5 ties cost $60, and 2 shirts and 3 ties cost $39. the cost of each shirt is 15.
Assuming that cost of shirt is x, cost of tie is y.
3x+5y=60, 2x+3y=39.
x=(39-3y)/2
3(30-3y)/72+5y=60,
y=120-117=3.
x=(39-3x3)/2
=30/2
=15.

A piggy bank contains $5.45 in dimes and quarters. If the bank contains 29 coins, 17 quarters are in the bank.
Assuming that number of dime is a , quarters is b,
a+b=29
0.1a+0.25b=5.45
a=29-b
0.1(29-b)+0.25b=5.45
b=17
a=29-17=12.
dimes are 12 , quarters are 17
