Answer 2

$\frac{6}{2x + 3} + \frac{4}{x - 2} = \frac{7}{x + 6} \\ \\ \\ = \frac{6}{5x} + \frac{4}{2x} \\ \\ when \: we \: cut \: 6 \: and \: 2x \\ \\ \frac{6}{5x} + \frac{4}{2x} = \frac{7}{6x} \\ \\ we \: have \: cut \: 6 \: and2x \: then \: in \: \\ 6 = 3 \\ 2x = > 1x \\ \\ \frac{3}{5x} + \frac{4}{1x} = \frac{7}{6x} answer \: \\ \\ mark \\ \\ my \\ \\ answer \\ \\ inbox$
