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 then multiply both sides by - 2, which gives me the final answer of m=50/3
