\(a)x=9/20-(-13/24)=>x=9/20+13/24=119/120\)
\(b)x=-2/5-13/15=-19/15\)
\(c)-x=-1/8+1/12=-1/24=>x=1/24\)
\(d)-4/9-x=5/36=>x=-4/9-5/36=-7/12\)

a.\(\Leftrightarrow x=\dfrac{9}{20}+\dfrac{13}{24}\Leftrightarrow x=\dfrac{119}{120}\)
b.\(\Leftrightarrow x=-\dfrac{2}{5}-\dfrac{13}{15}\Leftrightarrow x=\dfrac{-19}{15}\)
c.\(\Leftrightarrow-x=-\dfrac{1}{8}+\dfrac{1}{12}\Leftrightarrow-x=-\dfrac{1}{24}\Leftrightarrow x=\dfrac{1}{24}\)
d.\(\Leftrightarrow-x=\dfrac{5}{36}+\dfrac{4}{9}\Leftrightarrow x=-\dfrac{7}{12}\)
\(e.\Leftrightarrow\dfrac{x}{4}=\dfrac{31}{140}+\dfrac{3}{7}-\dfrac{2}{5}\Leftrightarrow\dfrac{x}{4}=\dfrac{1}{4}\Leftrightarrow x=1\)
