Thank you for the opportunity to help you with your question!

Well I understand how it feels to be unable to figure out what to do in such  a case. I will provide you with some materials to help you figure out what you can do. I will also give you links of where to find a detailed tutorial to solve the stalemate. in case you wont be able to do it by yourself, you can post the question here, let tutors have a look at it and  then they can solve it for you.

Start here with my example :

John bought 5 pairs of trousers and a 10 shirts for $200 and Tonny bought 20 pairs of trousers and 5 shirts for $250. Find the price of a pair of shoes and a shirt.

let shirt be s and Trousers be t

5t +10s=200

20t +5s= 250

We can eliminate one equation, say the first one by expressing t in terms of s

5t = 200-10s


Replace it in the other eq

20(40-2s) +5s=250





t= $15.71429

From here you can represent it in a graph by plotting the graph of the two lines, and the explanation you give is: The price of each is determined by the value of x, or y on the plane where the two lines meet.
