Method of Elimination and Substitution Method Questionnaire

will be required to identify at least three skills that this course has helped them develop—think broadly and creatively. I want to see you move beyond merely the historical content that we are learning in this course. What activities or assignments have we completed that have helped you mature academically or professionally? Maybe it has to do with meeting deadlines and maintaining a schedule. Maybe you want to focus on processing large amounts of data through readings and lectures. Maybe you have gotten better at note-taking and synthesizing complex information, or maybe your written communication skills have improved. For each of these skill sets, please identify which activities or assignments in this class have helped you develop professionally, and make it clear how these skills will help you in the future. To complete this assignment, students should write a 500-word reflection on the three skills that they have worked to develop in this course that will aid them in their future career goals.

1. (1 point) Use the method of elimination to solve the system
2x − 3y = −9,
−3x + 4y = 13.

5. (1 point) Solve the system
x + 4y
3x + 12y
Answer:
Note: If there is more than one point, type the points as a
comma separated list (e.g.: (1,2),(3,4)). If the system has no
solutions, enter None .
= 3,
= 9.
If the system has infinitely many solutions, express your answer
in the form x = x and y as a function of x
Your answer is
x=
y=

2. (1 point) Use the substitution method to solve the system
Answer(s) submitted:
−x + y = 6,
4x − 3y = −21.

Your answer is:
If there is more than one point, type the points separated by a
comma (i.e.: (1,2),(3,4)). If the system has no solution, type
none in the answer blank.

6. (1 point) Solve the system of equations.
(incorrect)
3. (1 point) Use a calculator solve the system

3x + 2y = 4,
x − 2y = 4.
x=
y=
Your answer is:
If there is more than one point, type the points separated by a
comma (i.e.: (1,2),(3,4)). If the system has no solution, type
none in the answer blank.
2x + y
x + 5y
= 17

4. (1 point) Use the elimination method to find all solutions
of the system
5x + 2y = 1,
7x + 3y = 2.
Your answer is:
If there is more than one point, type the points separated by a
comma (i.e.: (1,2),(3,4)). If the system has no solution, type
none in the answer blank.
7. (1 point)
