Answer:

n = 7

Step-by-step explanation:

5n + 12 = 9n - 16 (Given)

5n + 12 - 12 = 9n - 16 - 12 (Subtraction Property of Equality)

5n = 9n - 28 (Simplify)

5n - 9n = 9n - 9n - 28 (Subtraction Property of Equality)

-4n = -28 (Simplify)

[tex]\frac{-4n}{-4} = \frac{-28}{-4}[/tex] (Division Property of Equality)

n = 7 (Simplify)
