How can you determine the best method of solving an equation?

Be sure that you have downloaded the Discussion Guidelines and Discussion Rubric from the Review page of this lesson. Post your response to the following questions, being sure to address all parts of the question in your answer.

Part 1 (3 points) : When solving systems of equations, how do you determine what method to use?

Part 2 (10 points) : Choose 1 system of equations from the choices below. Then, solve the system and post your solution, showing your steps so that other students can see which method you chose.
• –y + 3x = 6
y = –6x + 12

• 6x – 4y = 54
–9x + 2y = –69

• 2y = x + 1
–2x – y = 7
