Answer & Solution
Correct answer: D. A solution
1. The rule for equations names a value that makes the equation true when substituted in as a solution.
2. A constant is a fixed number in the equation itself, not a value found by solving.
3. An expression or a coefficient could appear inside the equation, but neither word describes the value being sought.
