Answer 1

$(1 - x) + \frac{11}{48} = \frac{7}{48} + \frac{9}{48} \\ 1 - x = \frac{16}{48} - \frac{11}{48} \\ - x = \frac{5}{48} - 1 \\ - x = \frac{5}{48} - \frac{48}{48} \\ - x = - \frac{43}{48} \\ x = \frac{43}{48}$

$(x + \frac{5}{36} ) - \frac{7}{36} = 1 - \frac{19}{36} \\ x = 1 - \frac{19}{36} - \frac{5}{36} + \frac{7}{36} \\ x = \frac{36}{36} - \frac{19}{36} - \frac{5}{36} + \frac{7}{36} \\ x = \frac{19}{36}$

$(x - \frac{11}{29} ) + \frac{7}{29} = 1 - \frac{19}{29} \\ x = \frac{29}{29} + \frac{11}{29} - \frac{7}{29} - \frac{19}{29} \\x = \frac{14}{29}$

$1 - (x - \frac{3}{25} ) = \frac{1}{25} + \frac{9}{25} \\ 1 - x + \frac{3}{25} = \frac{10}{25} \\ - x = - 1 - \frac{3}{25} + \frac{10}{25} \\ - x = - \frac{25}{25} - \frac{3}{25} + \frac{10}{25} \\ - x = - \frac{18}{25} \\ x = \frac{18}{25}$
