MON IN PREPARATION FOR LESSON 3.07

CC ALGEBRA HOMEWORK SHEET WATCH THE VIDEO FOR Lesson 3.07 Danielle’s teacher asked her to come up with 2 manipulations that would not change the solution set for the equation 5n + 34 = −2(1 − 7n). First, she said that distributing the -2 on the right side of the equation would not change the solution set. She also said that subtracting 34 from the left side would not change the solution set. What is some possible feedback Danielle got from her teacher?

When asked the solution set for x2 = 81, Paul said 9. Is he completely correct? Why or why not?
