\left(a-6\right)\left(3\times 3+2\right)=3\times 3
Variable a cannot be equal to 6 since division by zero is not defined. Multiply both sides of the equation by 3\left(a-6\right), the least common multiple of 3,a-6.
\left(a-6\right)\left(9+2\right)=3\times 3
Multiply 3 and 3 to get 9.
\left(a-6\right)\times 11=3\times 3
Add 9 and 2 to get 11.
11a-66=3\times 3
Use the distributive property to multiply a-6 by 11.
11a-66=9
Multiply 3 and 3 to get 9.
11a=9+66
Add 66 to both sides.
11a=75
Add 9 and 66 to get 75.
a=\frac{75}{11}
Divide both sides by 11.
