Ta có:
11/15 - ( x + 1/3 ) = 2/5
=> x+1/3 =11/15 - 2/5
=>x+1/3 =1/3
=>x=1/3 - 1/3
=>x=0
NHỚ TK MK NHA
\(\frac{11}{15}-\left(x+\frac{1}{3}\right)=\frac{2}{5}\)
\(\frac{11}{15}-x-\frac{1}{3}=\frac{2}{5}\)
\(\frac{11}{15}-x-\frac{5}{15}=\frac{6}{15}\)
\(-x=\frac{6}{15}-\frac{11}{15}+\frac{5}{15}\)
\(-x=0\)
\(x=0\)

\(\frac{11}{15}-\left(x+\frac{1}{3}\right)=\frac{2}{5}\)
\(x+\frac{1}{3}=\frac{11}{15}-\frac{2}{5}\)
\(x+\frac{1}{3}=\frac{11}{15}-\frac{6}{15}\)
\(x+\frac{1}{3}=\frac{5}{15}\)
\(x=\frac{5}{15}-\frac{1}{3}\)
\(x=\frac{5}{15}-\frac{5}{15}\)
\(x=0\)
11/15 - ( x + 1/3 ) = 2/5
x+1/3 = 11/15 - 2/5
x+ 1/3 = 5/15
x = 5/15 - 1/3
x = 0/9
