$\frac{-81}{a - 2} = -9$

 - 81 = - 9 ( a - 2 )
-81 = -9a + 18
-81 - 18 =- 9a
-99 =- 9a 
-99 /- 9 = a
11 = a

Answer 2

The answer is given below :

Now,

$\frac{ - 81}{A - 2} = - 9 \\ \\ or, \: \: - 81 = - 9(A - 2) \\ \\ or, \: \: - 81 = - 9A + 18 \\ \\ or, \: \: 9A = 18 + 81 \\ \\ or, \: \: 9A = 99 \\ \\ or, \: \: A = \frac{99}{9} \\ \\ or, \: \: A = 11$

Thus, the required solution is A = 11.

Thank you for your question.
