a) \(x=\frac{7}{25}+\frac{-1}{5}\)
\(\Rightarrow x=\frac{2}{25}\)
Vậy \(x=\frac{2}{25}\)
b) \(x=\frac{5}{11}+\frac{4}{-9}\)
\(\Rightarrow x=\frac{1}{99}\)
Vậy \(x=\frac{1}{99}\)
c) \(\frac{5}{9}+x=\frac{-1}{3}\)
\(\Rightarrow x=\frac{-1}{3}-\frac{5}{9}\)
\(\Rightarrow x=\frac{-8}{9}\)
Vậy \(x=\frac{-8}{9}\)
d) \(\frac{3}{4}-x=-1\)
\(\Rightarrow x=\frac{3}{4}-\left(-1\right)\)
\(\Rightarrow x=\frac{7}{4}\)
Vậy \(x=\frac{7}{4}\)
e) \(x+4=\frac{1}{5}\)
\(\Rightarrow x=\frac{1}{5}-4\)
\(\Rightarrow x=\frac{-19}{5}\)
Vậy \(x=\frac{-19}{5}\)
f) \(x-\frac{1}{5}=2\)
\(\Rightarrow x=2+\frac{1}{5}\)
\(\Rightarrow x=\frac{11}{5}\)
Vậy \(x=\frac{11}{5}\)
g) \(x+\frac{5}{3}=\frac{1}{81}\)
\(\Rightarrow x=\frac{1}{81}-\frac{5}{3}\)
\(\Rightarrow x=\frac{-134}{81}\)
Vậy \(x=\frac{-134}{81}\)
