Short Answer

Expert verified

The solution of the given equation is $a = 0 .$

Step by step solution

Step 1. Given information

The given equation is $9 (6 a + 8) + 9 = 81$ .

We have to solve the given equation.

Step 2. Solving the given equation

$\begin{array}{l} Now, \\ \Rightarrow 9 (6 a + 8) + 9 = 81 \\ \Rightarrow 54 a + 72 + 9 = 81 [UsetheDistributiveProperty] \\ \Rightarrow 54 a + 81 = 81 [Combinetheliketerms] \\ \Rightarrow 54 a + 81 - 81 = 81 - 81 [Subtract 81 fromboththesides] \\ \Rightarrow 54 a = 0 \\ \Rightarrow \frac{54 a}{54} = \frac{0}{54} [Divideboththesidesby54] \\ \Rightarrow a = 0 \end{array}$
