Question

1: Which of the following equations could you solve by first adding six and then dividing by negative three?

3x - 6 = -9
6 - 3x = -9
-3x - 6 = -9
x/-3 + 6 = -9

2:
Which of the following is a solution of the equation 9 - 2x = -1?


-5
5
4
-4

3:
Alice solved the following equation:

-18 - 3x = 12
-3x = 6
x =-2

Which of the following statements is true?


Alice is correct.
The 6 should be 30 in step two.
The 6 should be -6 in step two.
The 6 should be -4 in step two.

Answer 1

1. C - You could add 6 and divide by negative three with this one

2. B - By plugging in five, you would get 9-10. and that would give you -1

3. B - You would add 18 to 12 to get 30
