Respuesta:

$\frac{x - 1}{ 3} + \frac{x - 2}{4} = \frac{x - 3}{6} \\ \frac{4(x - 1) + 3(x - 2)}{12} = \frac{x - 3}{6} \\ \frac{4x - 4 + 3x - 6}{12} = \frac{x - 3}{6} \\ \frac{7x - 10}{12} = \frac{x - 3}{6 } \\ 6(7x - 10) = 12(x - 3) \\ 42x - 60 = 12x - 36 \\ 42x - 12x = - 36 + 60 \\ 30x = 24 \\ x = \frac{24}{30} \\ x = \frac{4}{5}$

$3 + \frac{x + 1}{3} = \frac{x + 1}{6 } \\ \frac{3 \times 3 + 1 \times (x + 1)}{3} = \frac{x + 1}{6} \\ \frac{9 + x + 1}{3} = \frac{x + 1}{6} \\ \frac{x + 10}{3} = \frac{x + 1}{6 } \\ 6(x + 10) = 3(x + 1) \\ 6x + 60 = 3x + 3 \\ 6x - 3x = 3 - 60 \\ 3x = - 57 \\ x = \frac{ - 57}{3} \\ x = - 19$

$\frac{2x - 1}{2x + 2} = \frac{7}{10 } \\ 10(2x - 1) = (2x + 2)7 \\ 20x - 10 = 14x + 14 \\ 20x - 14x = 14 + 10 \\ 6x = 24 \\ x = \frac{24}{6} \\ x = 4$
