Answer 1

$\displaystyle 1)8\frac{4}{15}-5\frac{2}{5}x=4\frac{2}{3}\\\\ \frac{124}{15}-\frac{27}{5}x=\frac{14}{3}\\\\ 124-81x=70\\-81x=70-124\\-81x=-54\\\\ x=\frac{2}{3}\\\\ 2)7,625-(2\frac{1}{12}-x)=5\frac{23}{24}\\\\ \frac{61}{8}-(\frac{25}{12}-x)=\frac{143}{24}\\\\ \frac{61}{8}-\frac{25}{12}+x=\frac{143}{24}\\\\ \frac{133}{24}+x=\frac{143}{24}\\\\ x=\frac{143}{24}-\frac{133}{24}\\\\ x=\frac{5}{12}$
