3/4 (8 / 9 x+28)

Multiply $- \frac{3}{4}$ by $\frac{8}{9} x$:

$$- \frac{3}{4} \times \frac{8}{9} x = - \frac{3 \times 8}{4 \times 9} x = - \frac{24}{36} x$$

Simplify the fraction:

$$- \frac{24}{36} x = - \frac{2}{3} x$$

Multiply $- \frac{3}{4}$ by 28:

$$- \frac{3}{4} \times 28 = - \frac{3 \times 28}{4} = - \frac{84}{4}$$

Simplify the fraction:

$$- \frac{84}{4} = - 21$$

Combine the results from Step 1 and Step 2:

$$- \frac{2}{3} x - 21$$
