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 -m/2+8=-1/3, 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.
The student incorrectly multiplied both sides by –2.
C.
The final answer is not reduced or simplified.
D.
The mathematical work shown is correct.
