You have learned three methods to solve the system of equations. Recall that some methods work best for equations written in particular formats, yet any methods can be used to solve a system. Now that you have been challenged to solve many systems of equations in the lessons, you have built a good insight of each method. Given the following system of equations, how would you solve this system? Would you use substitution, elimination, or graphing? Why do you choose the method? What are the advantages of the method over the other methods?

3y = 12x + 15
3y = 15x + 24

Task 1

Choose a method of solving this system, substitution, elimination, or graphing, that you think would best help you solve this system.
Once you have selected the method, explain the advantages of using this method in writing.
Use very specific reasoning to justify your answer based on your understanding of math and what you have learned in this unit so far.
Remember there is no right or wrong answer.
Task 2

Post your explanation you wrote in Task 1.
In your post, make sure to include the following elements:
Which method you would use
The advantages of using the method
Specific reasoning to justify your explanation and solution if you have solved it.
