Answer & Solution
Correct answer: C. Both expressions equal 5
1. Simplify the first expression: 13 minus 8 equals 5. 2. Simplify the second expression: 13 plus negative 8 also equals 5. 3. Both expressions give the same result, which illustrates that subtracting 8 is the same as adding negative 8. _Source: OpenStax Elementary Algebra (CC BY 4.0), Ch 1 "Foundations", section 1.3 Add and Subtract Integers_
