Answer:
D. Solutions to equations simplify to a true statement when substituted back into the equation, whereas when solutions to inequalities are substituted, they may or may not satisfy the inequality.
Explanation:
An equation is a mathematical statement that shows that two expressions are equal to each other. The solution(s) to an equation is a value or set of values that make the equation true. When the solution(s) are substituted back into the equation, a true statement is obtained.
On the other hand, an inequality is a mathematical statement that shows that two expressions are not necessarily equal to each other but are related by a greater than, less than, or equal to symbol. The solution(s) to an inequality is a range of values that satisfy the inequality. When the solution(s) are substituted back into the inequality, a true or false statement is obtained depending on whether the values satisfy the inequality or not.
