To be solved, a **word** **problem** must be translated into the language of mathematics, where we use symbols for numbers - known or unknown, and for mathematical operations. First, circle what you're looking for— the __two__ numbers. The sum of twice one number and three times another number is 23 and their product is 20. __With__ each x value we can find its corresponding y value. Note: If a 1 button is dark blue, you have already 1'd it. (If you are not logged into your Google account (ex., g Mail, Docs), a window opens when you click on button, too.
