1)
$\frac{ {x}^{2} + 4x}{x + 2} = \frac{2x}{3} \\ 3( {x}^{2} + 4x) = 2x(x + 2) \\ 3 {x}^{2} + 12x = 2 {x}^{2} + 4x \\ 3{x}^{2} - 2 {x}^{2} + 12x - 4x = 0 \\ {x}^{2} + 8x = 0 \\ x(x + 8) = 0 \\ x = 0 \\ x + 8 = 0 \\ x = - 8$
Ответ: -8; 0.

2)
$\frac{c - 2}{c + 3} = \frac{c + 3}{c - 2} \\ {(c - 2)}^{2} = {(c + 3)}^{2} \\ {(c - 2)}^{2} - {(c + 3)}^{2} = 0 \\ (c - 2 + c + 3)(c - 2 - c - 3) = 0 \\ (2c + 1) \times ( - 5) = 0 \\ 2c + 1 = 0 \\ 2c = - 1 \\ c = - \frac{1}{2}$
Ответ: -1/2.
