In order to solve the equation 12x = -3(x + 1/3z) for x, a student simplifies the equation as shown:

Step 1: 12x = -3x + -2(1/3z)

Step 2: 12x = -3x + -z

Step 3: 12x – 3x = -z

Step 4: 9x = -z

Step 5: z = -9x

a)

The student missed a double negative 12x = -3x – (-z) in step 2.

b)

The student should have only multiplied x by -3 in step 1.

c)

The student subtracted 3x when he should have added 3x in step 3.

d)

The student should have kept the z on the right side in step 5.
