AU MAT 120 Systems of Linear Equations and Inequalities Discussion

Description

For the discussion board assignment in each unit, you will complete the problem associated with the letter that you have been assigned by the instructor. Post the entire example/word problem you have been assigned from the textbook. Then fully explain how you would go about finding the solution. Please explain all steps in a way that a struggling classmate could understand and learn from your methods.

Professional communication is expected in all posts, which includes proper spelling and grammar, and providing source information when using outside resources.

Each unit Discussion Forum will be worth 5 points and will be graded on the following criteria:

  • Problem is stated at the start of the post
  • All work/explanation for assigned problem is shown
  • Correct solution
  • Proper grammar and spelling are used

This is the Letter assigned to me below and the entire question to that letter.

R. Section 3.4

Solve the system by the method of your choice. If there is no solution or if there are infinitely many
solutions and a system’s equations are dependent, so state.

{ 3𝑥 − 5𝑦 = 7

𝑥 − 𝑦 = −1

BOTH EQUATION ARE IN THE BRACKET COULD’NT MAKE IT FIT BUT I ALSO ATTACH THE SHEET WITH THE PROBLEM AGAIN IT IS LETTER R
