Completed the following

In your initial discussion post, include the following:

• Identify the number assigned to you.
• State an application of a system of two lines in a financial context. Which of your systems would best describe it? (e.g. supply and demand, or car rental cost).
• Solve two assigned problems, showing the full solution process.
• Show full solutions for the two problems assigned to you. In the same original post, address the following two questions:
  • Two systems of linear equation problems
    • Solve by graphing, substitution, or eliminationthe solution is a single point. (Make sure that each solution is positive for x and y.) (Use the Desmos Video tutorialLinks to an external site., which shows how to solve systems of linear equations using the Desmos graphing calculator.)
    • Solve by graphingno solution or infinitely many solutions. (Use the Desmos Video tutorialLinks to an external site., which shows how to solve systems of linear equations using the Desmos graphing calculator.)

1	y = 50x y = 30x + 1, 500	4x - y = 1 -8x + 2y = 4
2	2x - y = 4 -5x + 3y = -9	x + y = 2 -2x - 2y = -4
3	2x- 2y = 6 2x + y = 3	4x - 2y = 1 -x + 1/2y = -1/4
4	x - y = 6 2x + 3y = 17	x + y = 2 2x + 2y = 5
5	x - 2y = 3 2x + 2y = 27	4x - 3y = 2 8x - 6y = 3
6	x - 2y = 3 2x + 2y = 27	4x - 3y = 2 8x - 6y = 3
7	2x - 3y = -8 5x + 4y = 3	0.9x - 0.9y = 1.8 0.3x - 0.3y = 0.6
8	60x + 80y = 200 11x + 21y = 43	Chapter 2, Question 6
9	2W + 2L = 240 W = 10 + L	Billie is considering buying a small rectangular lot. The perimeter of the lot is 160 feet. The width of the lot is 30 feet longer than the length. What are the dimensions of the lot?
10	Chapter 2, Question 1.	-3x + 3y = 4 -x + y = 3
11	Chapter 2, Question 2.	7x - y = 14 -7x + y = 10
12	Chapter 2, Question 3.	7x - y = 14 -7x + y = -14
