1ab +36 =ab1

Answer 1

\(\overline{1ab}+36=\overline{ab1}\)

\(\Rightarrow100+\overline{ab}+36=10.\overline{ab}+1\)

\(\Rightarrow136+\overline{ab}=10.\overline{ab}+1\)

\(\Rightarrow136-1=10.\overline{ab}-\overline{ab}\)

\(\Rightarrow135=9.\overline{ab}\)

\(\Rightarrow\overline{ab}=15\)

Answer 2

\(\overline{1ab}+36=\overline{ab1}\\ \Leftrightarrow100+\overline{ab}+36=10\cdot\overline{ab}+1\\ \Leftrightarrow100+36-1=10\cdot\overline{ab}-\overline{ab}\\ \Leftrightarrow135=9\cdot\overline{ab}\\ \Leftrightarrow\overline{ab}=15\)

Vậy \(a=1,b=5\)
