ayuda se los agradeceria mucho

Answer 1

$\frac{17}{4} - \frac{x}{6} = \frac{25}{12} \\ 51 - 2x = 25 \\ - 2x = 25 - 51 \\ - 2x = - 26 \\ x = - 26 \div ( - 2) \\ x = + 13$

$\frac{x}{3} + \frac{7}{9} = \frac{47}{45} \\ 15x + 35 = 47 \\ 15x = 47 - 35 \\ 15x = 12 \\ x = 12 \div 15 \\ x = \frac{4}{5}$

$\frac{x}{9} - \frac{4}{13} = - \frac{83}{312} \\ 104x - 288 = - 249 \\ 104x = - 249 + 288 \\ 104x = 39 \\ x = 39 \div 104 \\ x = \frac{3}{8}$

espero haberte ayudado
