Answer:
28 short-sleeved shirts were sold and 23 long-sleeved shirts were sold.
Step-by-step explanation:
We can solve this question by a system of equations.
I am going to say that:
x is the number of short-sleeved shirts sold.
y is the number of long-sleeved shirts sold.
A department store sold 51 shirts one day.
This means that 
All short-sleeved shirts cost $14.00 each and all long-sleeved shirts cost $23.00 each. Total receipts for the day were $921.00.
This means that

How many of each kind of shirt were sold?
We have to solve the system of equations.

Answer:
x = 5/6-4y^2
Step-by-step explanation:
^ = to the power of and * = times
y = square root of 6x-5/4x
(times by the square root on either side, sorry I don't know how to word it)
y^2=6x-5/4x
(times by 4x either side)
4xy^2= 6x-5
(+5 either side)
4xy^2+5=6x
(-4xy^2 either side)
5=6x-4xy^2
(factorize)
5=x(6-4y^2)
(divide by (6-4y^2))
5/6-4y^2 = x or x = 5/6-4y^2
Tell me if this is incorrect.
Decimal answer...I got 12.25 when added together.
