\(x+\frac{1}{2}\times\frac{1}{5}=\frac{3}{4}\)
\(x+\frac{1}{10}=\frac{3}{4}\)
\(x=\frac{3}{4}-\frac{1}{10}\)
\(x=\frac{13}{20}\)
\(x\)+ \(\frac{1}{2}\)x \(\frac{1}{5}\)= \(\frac{3}{4}\)
\(x\)+ \(\frac{1}{2}\) = \(\frac{3}{4}\): \(\frac{1}{5}\)
\(x\)+ \(\frac{1}{2}\) = \(\frac{15}{4}\)
\(x\) = \(\frac{15}{4}\)- \(\frac{1}{2}\)
\(x\) = \(\frac{13}{4}\)
