a)x+$\frac{3}{5}$=$\frac{1}{15}$
⇔x=$\frac{1}{15}$-$\frac{3}{5}$
⇔x=$\frac{-8}{15}$
Vậy x=$\frac{-8}{15}$
b)$\frac{-3}{6}$=$\frac{x}{-2}$
⇔x=$\frac{(-3)×(-2)}{6}$=1
Vậy x=1
$\frac{x}{-2}$=$\frac{-18}{y}$
⇔y=$\frac{(-2)×(-18)}{1}$ =36
Vậy y=36
c)$\frac{-6}{7}$+$\frac{3}{35}$<$\frac{x}{35}$<$\frac{-2}{5}$+$\frac{3}{7}$
⇔$\frac{-27}{35}$<$\frac{x}{35}$<$\frac{1}{35}$
⇒x thuộc -26,-25,-24,-23,-22,-21,-20.....-2,-1,0
