Answer 1

7ab + 37 = ab4 x 3

7ab + 37 = 12ab

7ab -12ab = -37

-5ab = -37

ab=37/5

Answer 2

\(\overline{7ab}+37=\overline{ab4}\times3\)

\(700+\overline{ab}+37=\left(\overline{ab}\times10+4\right)\times3\)

\(737+\overline{ab}=\overline{ab}\times30+12\)

\(737-12=\overline{ab}\times29\)

\(725=\overline{ab}\times29\)

\(\overline{ab}=725:29=25\)
