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 35x – 10 = 5, I must solve for x. I first divide both sides by 35, which results in the equation x - 10=1/7 I then add 10 to both sides, which gives me my final answer of x=71/70
