\(\left(4\frac{1}{11}-3.x\right).2\frac{1}{5}=4\frac{1}{5}\)
=>\(\left(\frac{45}{11}-3.x\right).\frac{11}{5}=\frac{21}{5}\)
\(\frac{45}{11}-3x=\frac{21}{5}.\frac{5}{11}\)
\(\frac{45}{11}-3x=\frac{21}{11}\)
\(3x=\frac{45}{11}-\frac{21}{11}\)
\(3x=\frac{24}{11}\)
\(x=\frac{24}{11}:3=\frac{24}{11.3}\)
\(x=\frac{8}{11}\)
