[tex]1) \: \frac{8}{2x} = \frac{4}{x} [/tex]
[tex]2) \frac{3x - 9 + 2x + 4}{(x + 2)(x - 3)} = \frac{5(x - 1)}{(x + 2)(x - 3)}[/tex]
[tex]3) \: \frac{4x - 4 - 5x - 15}{(x + 3)(x - 1)} = \frac{ - (x + 19)}{(x + 3)(x - 1)} [/tex]
[tex]4) \: \frac{2x - 6xy}{18x} = \frac{2x(1 - 3y)}{18x} = \frac{1 - 3y}{9} [/tex]
[tex]5) \: \frac{3}{(x + 3)} \times ( \frac{4}{(x - 3)}+ \frac{x - 3}{x - 3}) = \frac{3}{x + 3} \times ( \frac{x + 1}{x - 3} ) = \frac{3x + 3}{ {x}^{2} - 9} [/tex]
[tex]6) \: \frac{x - y - 2x - 2y}{ {x}^{2} - {y}^{2}} \times \frac{ {x}^{2} - {y}^{2}}{3x + 3y + 4x - 4y} = \frac{ - (x + 3y)}{7x - y} [/tex]
