Shirts = $7
Shorts $17
Step-by-step explanation:

T - shirts
S - shorts
We can make two equations out of this problem:
4T + 3S = $79
7T + 8S = $185
Through substitution we can solve for one of the unknowns. We make one equation to solve for an unknown
We use the formula of S and insert it into the other equation:

Now that we know T, we can use it to solve for the other unknown. You can use it on any of the formulas.
We know then that Shorts are $17 each.
