Explicación paso a paso:

$a)x+\frac{3}{5}=-2\\\\x+\frac{3}{5}-\frac{3}{5}=-2-\frac{3}{5}\\\\x=-\frac{13}{5}\\\\b)x+\frac{1}{4}=8\\\\x+\frac{1}{4}-\frac{1}{4}=8-\frac{1}{4}\\\\x=\frac{31}{4}\\\\c)x+\frac{3}{7}=4\\\\x+\frac{3}{7}-\frac{3}{7}=4-\frac{3}{7}\\\\x=\frac{25}{7}\\\\d)x+\frac{5}{6}=1\\\\x+\frac{5}{6}-\frac{5}{6}=1-\frac{5}{6}\\\\x=\frac{1}{6}\\\\e)x-\frac{1}{3}=3\\\\x-\frac{1}{3}+\frac{1}{3}=3+\frac{1}{3}\\\\x=\frac{10}{3}\\\\f)x-\frac{1}{5}=6\\\\x-\frac{1}{5}+\frac{1}{5}=6+\frac{1}{5}$

$x=\frac{31}{5}\\\\g)x-\frac{1}{2}=5\\\\x-\frac{1}{2}+\frac{1}{2}=5+\frac{1}{2}\\\\x=\frac{11}{2}\\\\h)x-\frac{2}{7}=-1\\\\x-\frac{2}{7}+\frac{2}{7}=-1+\frac{2}{7}\\\\x=-\frac{5}{7}\\\\i)x-\frac{2}{3}=9\\\\x-\frac{2}{3}+\frac{2}{3}=9+\frac{2}{3}\\\\x=\frac{29}{3}$
