$\displaystyle 1)x-18\frac{1}{5}=2\frac{7}{15}\\ \\x-\frac{91}{5}=\frac{37}{15}\\ \\x=\frac{37}{15}+\frac{91}{5}\\ \\x=\frac{62}{3}=20\frac{2}{3}\\ \\2)(x-2\frac{7}{8})+3\frac{5}{6}=4\frac{2}{3}\\ \\(x-\frac{23}{8})+\frac{23}{6}=\frac{14}{3}\\ \\x-\frac{23}{8}+\frac{23}{6}=\frac{14}{3}\\ \\x+\frac{23}{24}=\frac{14}{3}\\ \\x=\frac{14}{3}-\frac{23}{24}\\ \\x=\frac{89}{24}=3\frac{17}{24}$
