$\frac{2}{3}x + \frac{7}{12} = \frac{11}{6} * \frac{6}{11}$
$\frac{2}{3} x = 1 - \frac{7}{12}$
$x = \frac{5}{12} * \frac{3}{2}$
$x = \frac{5}{8}$
-------------------------------------------------
$3 \frac{2}{3} y = 1 \frac{1}{6} - \frac{1}{6} + 3 \frac{7}{12}$
$3 \frac{2}{3} y = 4 \frac{7}{12}$
$y = \frac{55}{12} * \frac{3}{11} = \frac{5}{4}$
$y = 1 \frac{1}{4}$
