Answer 1

\(\left(\frac{7}{2}+2x\right).\frac{8}{3}=\frac{16}{3}\)

 \(\frac{7}{2}+2x=\frac{16}{3}:\frac{8}{3}\)

 \(\frac{7}{2}+2x=2\)

 \(2x=2-\frac{7}{2}\)

\(2x=\frac{-3}{2}\)

\(x=\frac{-3}{2}:2\)

\(x=\frac{-3}{4}\)

Answer 2

\(\frac{1}{3}.x+0,5x=0,75\)

\(\frac{1}{3}x+\frac{1}{2}x=\frac{3}{4}\)

\(x.\left(\frac{1}{3}+\frac{1}{2}\right)=\frac{3}{4}\)

\(x.\frac{5}{6}=\frac{3}{4}\)

\(x=\frac{3}{4}:\frac{5}{6}\)

\(x=\frac{9}{10}\)
