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

Answer 1

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

\(\frac{5}{3}+x=\frac{7}{3}\)

\(x=\frac{7}{3}-\frac{5}{3}\)

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

Answer 2

\(\frac{5}{3}+x=\frac{7}{3}\)

\(x=\frac{7}{3}-\frac{5}{3}\)

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

Answer 3

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

   \(\frac{5}{3}+x=\frac{7}{3}\)

              \(x=\frac{7}{3}-\frac{5}{3}\)

              \(x=\frac{2}{3}\)
