Ответ: -6,5
[tex] \frac{5}{x - 1} = \frac{3}{x + 2} \\ 5x + 10 = 3x - 3 \\ 5x - 3x = - 3 - 10 \\ 2x = - 13 \\ x = - 6.5[/tex]
Ответ: 3 ; -3
[tex] \frac{ {x}^{2} + 4x }{x - 3} - \frac{4x + 9}{x - 3} = 0 \\ {x}^{2} + 4x - 4x - 9 = 0 \\ {x}^{2} - 9 = 0 \\ (x - 3)(x + 3) = 0 \\ x - 3 = 0 \: \: \: \: \: \: \: \: \: \: x + 3 = 0 \\ x = 3 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: x = - 3[/tex]
