7/3 ( x + 9/28 ) = 20
x + 9/28 = 20 ÷ 7/3 = (20 × 3)/7 = 60/7
x = 60/7 - 9/28
x = 240/28 - 9/28
x = 231/28

$\frac{7}{3} (x + \frac{9}{28} ) = 20 \\ \\ \frac{1}{3} (x + \frac{9}{28} ) = \frac{20}{7} \\ \\ \frac{x}{3} + \frac{9}{28 \times 3} = \frac{20}{7} \\ \\ \frac{x}{3} + \frac{9}{84} = \frac{20}{7} \\ \\ \frac{x}{3} = \frac{20}{7} - \frac{3}{28} \\ \\ \frac{x}{3} = \frac{11}{4} \\ \\ x \frac{11}{4} \times 3 \\ \\ x = \frac{33}{4} \\ \\$

The answer is: x = 33/4 or x = 8.25.
