Question

A student is attempting to solve a multi-step equation. Sample mathematical work is shown below. Which statement best applies to the sample mathematical work?
Given the equation 2003-05-05-00-00_files/i0300000.jpg, I must solve for m. I first subtract 8 from both sides, which gives me 2003-05-05-00-00_files/i0300001.jpg. I then multiply both sides by –2, which gives me the final answer of 2003-05-05-00-00_files/i0300002.jpg.
A.

The student incorrectly subtracted 8 from both sides.
B.

The student incorrectly multiplied both sides by –2.
C.

The final answer is not reduced or simp

Answer 3

A student is attempting to solve a multi-step equation. Sample mathematical work is shown below. Which statement best applies to the sample mathematical work?
Given the equation , I must solve for m. I first subtract 8 from both sides, which gives me \[-m/2\] = -25/3. I then multiply both sides by –2, which gives me the final answer of m=50/3
A.

The student incorrectly subtracted 8 from both sides.
B.
