Justins house sits kn a lot that is shaped like a trapezoid. He decides to make the back part of the lot useable by building a triangular dog pen for his dog. On his lunch break at work he decides to order the materials but realizes that he forgot to write down the actual dimensions of that area of the lot. He wants to get the pen done this weekend because his biddies are coming over to help him, so he has to order the materials today in order for them to arrive on time. He remembers that one side is 5 feet more than the length of the shortest side a f longest side is 10 feet more than the shortest side. Can he figure out the dimensions of the area so that he can order the materials today?

3x + 2y = 12
subtract 3x from both sides
2y = -3x + 12
divide all terms by 2 so that you can have only the y on the left side
y = -3/2x + 6
And that is your answer!

Hope this helped!! :)
