Question 11(Multiple Choice Worth 5 points)
(07.03 LC)
The steps below show the incomplete solution to find the value of m for the equation 4m β 2m + 4 = β1 + 13:
Step 1: 4m β 2m + 4 = β1 + 13
Step 2: 4m β 2m + 4 = 12
Step 3: 2m + 4 = 12
Which of these is most likely the next step?
2m = 3
2m = 8
2m = 16
2m = 18
Question 12(Multiple Choice Worth 5 points)
(07.05 HC)
The work of a student to solve the equation 4(2x β 4) = 8 + 2x + 8 is shown below:
Step 1: 4(2x β 4) = 8 + 2x + 8
Step 2: 6x β 8 = 16 + 2x
Step 3: 6x β 2x = 16 + 8
Step 4: 4x = 24
Step 5: x = 6
In which step did the student first make an error and what is the correct step?
Step 2; 8x β 4 = 2(6 + x + 6)
Step 2; 8x β 16 = 16 + 2x
Step 3; 6x β 2x = 16 β 8
Step 3; 6x + 2x = 16 + 8
