T=Tshirts
S=shorts
T= 2S
I know half as much shorts were sold and doubling the number of shorts would give me the number of tshirts.
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 Tshirts sold.
