I do my school through a program on the computer. (I took a screenshot of my problem below) It's just an example problem, so your not cheating for me haha. NOTE! The question that this is a solution to is "Find the two consecutive odd numbers such that the sum of two-sevenths of the smaller and one-third of the larger is equal to thirty-one. I'm pretty sure I understand everything but what I have circled (in the picture below). Where did 31 come from?
