**Infinity_plus_one**, Friday, August 22, 2008 at 7:04pmT=T-shirts

S=shorts

T= 2S

I know half as much shorts were sold and doubling the number of shorts would give me the number of t-shirts.

9T + 14S = 256

Because I know that T=2S, I could replace the T with 2S.

9(2S)+14S=256

By using substitution, I have one variable to work with.

Solve for s to find the number of shorts sold.

Then, you can plug it back into T=2S and solve for T to find the number of T-shirts sold.
