Answer:

n = 11

General Formulas and Concepts:

• Order of Operations: BPEMDAS
• Equality Properties
• Vertical Angles: Angles that are across from each other and are congruent

Step-by-step explanation:

Step 1: Set up equation

Vertical angles must be congruent.

(6n - 4)° = (5n + 7)°

Step 2: Solve for n

1. Subtract 5n on both sides:                    n - 4 = 7
2. Add 4 to both sides:                               n = 11
