Question

[Nguyễn Trần Thái Ny]

x+31/10 =14,5+12/10

Answer 1

[Han Sara ft Tùng Maru]

\(x+\frac{31}{10}=14,5+\frac{12}{10}\)

\(x+\frac{31}{10}=\frac{29}{2}+\frac{12}{10}\)

\(x+\frac{31}{10}=\frac{157}{10}\)

\(x=\frac{157}{10}-\frac{31}{10}\)

\(x=\frac{63}{5}\)

Answer 2

[Nguyễn Thanh Hiền]

\(x+\frac{31}{10}=14,5+\frac{12}{10}\)

\(\Rightarrow x+\frac{31}{10}=\frac{157}{10}\)

\(\Rightarrow x=\frac{157}{10}-\frac{31}{10}\)

\(\Rightarrow x=\frac{63}{5}\)

Vậy  \(x=\frac{63}{5}\)
