Answer:

9(n - 9)  = 9n - 81

Step-by-step explanation:

Equivalent expressions are expressions which are equal . To determine if expressions are equivalent, simplify to lowest terms through combining like terms.

-9 - 7n + 16n  =  -9 + 9n

9(n - 9)  = 9n - 81

n - 9 + 8n  = -9 + 9n

9n - 9 = -9 + 9n

Answer-9(n - 9) = 9n - 81

Step-by-step explanation:

"Equivalent expressions are expressions which are equal . To determine if expressions are equivalent, simplify to lowest terms through combining like terms."

-9 - 7n + 16n = -9 + 9n-equivalent

9(n - 9) = 9n - 81 -not equivalent

n - 9 + 8n = -9 + 9n-equivalent

9n - 9 = -9 + 9n-equivalent
