Answer:

\frac{xy + 35 - 5x - 7y}{xy - 2x - 7y + 14} ÷ \frac{y^2 - 2y - 15}{y^2 - 4} =\frac{y + 2}{y + 3}

Step-by-step explanation:

\frac{xy + 35 - 5x - 7y}{xy - 2x - 7y + 14} ÷ \frac{y^2 - 2y - 15}{y^2 - 4}

=\frac{xy - 5x - 7y + 35}{x(y - 2) - 7(y - 2)} x \frac{(y + 2)(y - 2)}{y^2 - 5y + 3y - 15}

=\frac{x(y - 5) - 7(y -5)}{(y - 2)(x - 7)} x \frac{(y + 2)(y - 2)}{(y - 5)(y + 3)}

=\frac{(y - 5)(x - 7)}{(x - 7)} x \frac{(y + 2)}{(y - 5)(y + 3)}

=\frac{y + 2}{y + 3}
