\(\frac{1-\frac{2}{10}+x+\frac{1}{5}}{\frac{4}{3}-\frac{2}{3}+\frac{10}{3}}-1=\frac{3}{2}\)
\(\Rightarrow\frac{\frac{4}{5}+x+\frac{1}{5}}{\frac{4-2+10}{3}}=\frac{3}{2}+1\)
\(\Rightarrow\frac{\left(\frac{4}{5}+\frac{1}{5}\right)+x}{4}=\frac{5}{2}\)
\(\Rightarrow1+x=\frac{5}{2}.4\)
\(\Rightarrow1+x=10\)
\(\Rightarrow x=10-1\)
\(\Rightarrow x=9\)
Vậy x = 9
_Chúc bạn học tốt_
(1-2/10+x+1/5)/(4/3-2/3+10/3)=3/2+1
(1-2/10+x+1/5)/(4/3-2/3+10/3)=5/2
=>1-2/10+x+1/5=5
=>8/10+x=5-1/5
=>4/5+x=24/5
=>x=24/5-4/5
=>x=4
