question
solve for ( a ).
( 20 + \frac{2}{9}a = 38 )

Explanation:

Step1: Subtract 20 from both sides

$20 + \frac{2}{9}a - 20 = 38 - 20$
$\frac{2}{9}a = 18$

Step2: Multiply by $\frac{9}{2}$ on both sides

$\frac{2}{9}a \times \frac{9}{2} = 18 \times \frac{9}{2}$
$a = 9 \times 9$

Answer:

$a = 81$
