Answer:

$\frac{31x-159}{168y}$

Step-by-step explanation:

$\frac{x-4}{7y}$ - $\frac{x+7}{8y}$ + $\frac{x+3}{6y}$

the LCD of the denominators is 168y , then

$\frac{24(x-4)-21(x+7)+28(x+3)}{168y}$ ← distribute and simplify numerator

= $\frac{24x-96-21y-147+28x+84}{168y}$

= $\frac{31x-159}{168y}$
