\(a)x=9/20-(-13/24)=>x=9/20+13/24=119/120\)

\(b)x=-2/5-13/15=-19/15\)

\(c)-x=-1/8+1/12=-1/24=>x=1/24\)

\(d)-4/9-x=5/36=>x=-4/9-5/36=-7/12\) 

22 tháng 2 2022

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.\(\Leftrightarrow-x=\dfrac{5}{36}+\dfrac{4}{9}\Leftrightarrow x=-\dfrac{7}{12}\)

\(e.\Leftrightarrow\dfrac{x}{4}=\dfrac{31}{140}+\dfrac{3}{7}-\dfrac{2}{5}\Leftrightarrow\dfrac{x}{4}=\dfrac{1}{4}\Leftrightarrow x=1\)

f.\(ĐK:x\ne0\)

\(\Leftrightarrow\dfrac{5}{x}=\dfrac{1}{2}-\dfrac{5}{12}+\dfrac{1}{8}\Leftrightarrow\dfrac{5}{x}=\dfrac{5}{24}\Leftrightarrow x=24\left(tm\right)\)

g.\(\Leftrightarrow x=\dfrac{11}{10}-\dfrac{1}{9}\Leftrightarrow x=\dfrac{89}{90}\)

h.\(\Leftrightarrow\dfrac{5-x}{12}=\dfrac{3}{8}-\dfrac{7}{24}\Leftrightarrow\dfrac{5-x}{12}=\dfrac{1}{12}\Leftrightarrow5-x=1\Leftrightarrow x=4\)
