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