Answer 1

$\frac{ \frac{x - 5}{3} - \frac{x - 7}{4} }{ \frac{x + 5}{6} - \frac{x + 7}{3} } = - \frac{3}{4} \\ \frac{ \frac{4(x - 5) - 3(x - 7)}{12} }{ \frac{x + 5 - 2(x + 7)}{6} } = - \frac{3}{4} \\ \frac{ \frac{4x - 20 - 3x + 21}{12} }{ \frac{x + 5 - 2x - 14}{6} } = - \frac{3}{4} \\ \frac{ \frac{x + 1}{12} }{ \frac{ - x - 9}{6} } = - \frac{3}{4} \\ \frac{6(x + 1)}{12( - x - 9)} = - \frac{3}{4} \\ \frac{x + 1}{ - 2x - 18} = - \frac{3}{4} \\ - 4(x + 1) = 3( - 2x - 18) \\ - 4x - 4 = - 6x - 54 \\ 6x - 4x = - 54 + 4 \\ 2x = - 50 \\ x = - 50 \div 2 \\ x = - 25$
