Answer 2

Step-by-step explanation:

Here is your answer.....

$27 \times \frac{ { - 1}^{3} }{ {3}^{3} } - a \times {( \frac{ - 1}{3} )}^{2} - ( \frac{ - 1}{3} ) + 3 = 0 \\ 27 \times \frac{ - 1}{27} - \frac{1}{9} + \frac{1}{3} + 3 = 0 \\ - 1 - \frac{1}{9} a + \frac{1 + 9}{3} = 0 \\ - 1 + \frac{10}{3} - \frac{1}{9} a = 0 \\ \frac{ 7}{3} - \frac{1}{9} a = 0 \\ \frac{7}{3 } = \frac{1}{9} a \\ a = \frac{7}{3} \times 9 \\ a = 21$
