Answer 1

Answer:

$\frac{2x}{x+7}$

Step-by-step explanation:

we have

$(\frac{x-3}{x+7})(\frac{2x}{x-3})$

When multiply two fractions:

Multiply the numerators of the fractions to get the new numerator.

Multiply the denominators of the fractions to get the new denominator

so

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

(x-3) cancels out

$\frac{2x}{x+7}$
