The steps below show the incomplete solution to find the value of n for the equation 4n – 2n + 4 = –1 + 17:

Step 1: 4n – 2n + 4 = –1 + 17

Step 2: 4n – 2n + 4 = 16

Step 3: 2n + 4 = 16

Which of these is most likely the next step? (5 points)


2n = 20
2n = 12
2n = 4
2n = 8

The work of a student to solve the equation 3(2x – 4) = 8 + 2x + 6 is shown below:

Step 1: 3(2x – 4) = 8 + 2x + 6

Step 2: 5x – 7 = 14 + 2x

Step 3: 5x – 2x = 14 + 7

Step 4: 3x = 21

Step 5: x = 7

In which step did the student first make an error and what is the correct step? (5 points)



Step 3; 5x – 2x = 14 – 7
Step 2; 6x – 7 = 2(6 + x + 4)
Step 2; 6x – 12 = 14 + 2x
Step 3; 5x + 2x = 14 + 7
