17 white sweatshirts were sold and 19 yellow sweatshirts were sold.
Step-by-step explanation:

Solve the system. I'll use substitution this time (though elimination will work just as perfect). From the first equation, subtract <em>w</em> from both sides:
Substitute this into the second:
Distribute:
Simplify:
Divide both sides by -0.55:
So, 17 white sweatshirts were sold.
Using the modified equation, substitute:
Therefore, 17 white sweatshirts were sold and 19 yellow sweatshirts were sold.
