\(1020+Xx\frac{1}{3}=\frac{4}{5}+1020\)
\(=1020+Xx\frac{1}{3}=\frac{5104}{5}\)
\(=Xx\frac{1}{3}=\frac{5104}{5}-1020\)
\(=Xx\frac{1}{3}=\frac{4}{5}\)
\(=\frac{4}{5}:\frac{1}{3}\)
\(=\frac{12}{5}\)
\(1020+x.\frac{1}{3}=\frac{4}{5}+1020\)
\(1020+x.\frac{1}{3}=\frac{5104}{5}\)
\(x.\frac{1}{3}=\frac{5104}{5}-1020\)
\(x.\frac{1}{3}=\frac{4}{5}\)
\(x=\frac{4}{5}:\frac{1}{3}\)
\(x=\frac{12}{5}\)

\(1020+x\cdot\frac{1}{3}=\frac{4}{5}+1020\)
\(1020+x\cdot\frac{1}{3}=\frac{5104}{5}\)
\(x\cdot\frac{1}{3}=\frac{5104}{5}-1020\)
\(x\cdot\frac{1}{3}=\frac{4}{5}\)
\(x=\frac{4}{5}\div\frac{1}{3}\)
