Answer 3

Gọi x là số cần tìm
\(621=32 . x+13\)
          \(32.x=621-13\)
          \(32 . x=608\)
               \(x=608 : 32\)
               \(x=19\)
          

Answer 4

\(621 = 32 . 19 + 13\)

Answer 5

\(621=32\times....+13\)

\(\Rightarrow32\times....+13=621\)

\(\Rightarrow32\times x=621-13\)

\(\Rightarrow32\times x=608\)

\(x=608\div32\)

\(x=19\)
