$\tt a)~\sf\dfrac{x}{6}-\dfrac{a}{3}=\dfrac{b}{2}\\\sf\backslash\!\!\!6\cdot\dfrac{x}{\backslash\!\!\!6}-\backslash\!\!\!6^2\cdot\dfrac{a}{\backslash\!\!\!3}=\backslash\!\!\!6^3\cdot\dfrac{b}{\backslash\!\!\!2}\\\sf x-2a=3b\\\huge\boxed{\boxed{\boxed{\boxed{\sf x=2a+3b\checkmark}}}}$

$\tt b)~\sf\dfrac{x}{3}+a=c-4a\\\sf\backslash\!\!\!3\cdot\dfrac{x}{\backslash\!\!\!3}+3a=3c-12a\\\sf x=3c-12a-3a\\\huge\boxed{\boxed{\boxed{\boxed{\sf x=3c-15a\checkmark}}}}$
