General Formulas and Concepts:

Pre-Algebra

• Order of Operations: BPEMDAS
• Equality Properties

Explanation:

Step 1: Define equation

13 - 2(4r - 5) = -(7 + 8r)

Step 2: Solve for r

1. Distribute: 13 - 8r + 10 = -7 - 8r
2. Combine like terms: -8r + 13 = -7 - 8r
3. Add 8r on both sides: 13 ≠ -7

Here, we see that 13 does not equal -7. ∴ r has no solutions.
