[tex](x - 2 \frac{7}{8} ) + 3 \frac{5}{6} = 4 \frac{2}{3} \\ x - 2 \frac{21}{24} + 3 \frac{20}{24} = 4 \frac{2}{3} \\ x + \frac{23}{24} = 4 \frac{2}{3} \\ x = 4 \frac{16}{24} - \frac{23}{24} \\ x = 3 \frac{17}{24} [/tex]

[tex](x - \frac{23}{8}) + \frac{23}{6} = \frac{14}{ 3} \\ x - \frac{23}{8} + \frac{23}{6} = \frac{14}{3} \\ x + \frac{23}{24} = \frac{14}{3} \\ x = \frac{14}{3} - \frac{23}{24} \\ x =3 \frac{17}{24} [/tex]
