Answer:
r = no solutions
General Formulas and Concepts:
Pre-Algebra
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
Step 1: Define equation
13 - 2(4r - 5) = -(7 + 8r)
Step 2: Solve for r
- Distribute: 13 - 8r + 10 = -7 - 8r
- Combine like terms: -8r + 13 = -7 - 8r
- Add 8r on both sides: 13 ≠ -7
Here, we see that 13 does not equal -7. ∴ r has no solutions.
