T-Shirts and Shorts

Subject: How many of each were sold?

I need an equation for this problem:

In the evening, a sporting goods store sells twice as many T-shirts 
as shorts. T-shirts are $9 dollars each, and shorts are $14 each. 
The total amount of money taken in for both items was $256. 

Find the number of each that was sold. 

The answer is 16 T-shirts and 8 pairs of shorts.

Thanks,
Dustin

Let x be the number of shorts sold.  Then 2x must be the number of 
T-shirts sold.  Now calculate the total amount of money gathered.

  14x + 9(2x) = 256

It's quite simple if you just name your variable, write expressions in 
terms of the variable and then write an equation from the information 
given.
