Ok, so first, you need two variables to set up the system. Let's call the plain wrapping paper "p" and the holiday wrapping paper "h" for convenience. Next, we have to convert the words into math, which is the hardest part of every word problem. Make sure you break it down into sections and read all the numbers carefully. It says that Brenda sold 2 rolls of plain wrapping paper and 1 roll of holiday wrapping paper. That means for Brenda, we can rewrite her sales using the expression "2p + h" and because she made $41, we get the first equation "2p + h = 41." Next, we do the same thing for Jessica. She sold 7 rolls of plain wrapping paper and 1 roll of holiday wrapping paper, so that's "7p + h." She made $106 in total, so we have our second equation, "7p + h = 106." These two equations together are the system, which can be solved to find the specific values of "p" and "h" which you can do by elimination.
