Concepts

After solving an equation in a word problem, a student gets $x = -6$ .
The problem asks for the number of boxes shipped. Which is the correct
next step?

Report $-6$ as the answer because it satisfies the equation.

Report $6$ because all word-problem answers must be positive.

Check whether $x = -6$ makes sense in context. Since a negative
number of boxes is not possible, the problem has no viable solution
from this model.

Re-solve the equation until a positive answer is found.
