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)
