The expression $x = \frac{5}{6} + \frac{15}{18} - \frac{10}{12}$ may be simplified considerably:
$x = \frac{5}{6} + \frac{15}{18} - \frac{10}{12}$
$= \frac{5}{6} + (\frac{30}{36} - \frac{30}{36})$
$= \frac{5}{6}$
Thus, $x - 1 = - \frac{1}{6}$ and $3 (x - 1) = - \frac{1}{2}$
${(x - 1)}^{3} = - \frac{1^{3}}{6^{3}} = - \frac{1}{216} .$

x = \frac{5}{6} + \frac{15}{18} - \frac{10}{12}

x - 1 = \frac{5}{6} + \frac{15}{18} - \frac{10}{12} - \frac{3}{3}

(x - 1) 3 = (\frac{5}{6} + \frac{15}{18} - \frac{10}{12} - \frac{3}{3}) 3

(x - 1) 3 = 3 \cdot \frac{5}{6} + 3 \cdot \frac{15}{18} - 3 \cdot \frac{10}{12} - 3 \cdot \frac{3}{3}

(x - 1) 3 = \frac{5}{2} + \frac{15}{6} - \frac{10}{4} - 3

(x - 1) 3 = \frac{5}{2} + \frac{5}{2} - \frac{5}{2} - 3

(x - 1) 3 = \frac{5}{2} - 3

(x - 1) 3 = \frac{5}{2} - \frac{6}{2}

(x - 1) 3 = - \frac{1}{2}
