Answer:

• let the number be x

• Mathematical interpretation and manipulation of the above statement:

$\hookrightarrow \: { \tt{13 - 3x = 5 + x}}$

• solve and simplify:

${ \tt{x + 3x = 13 - 5}} \\ \\ { \tt{4x = 8}} \\ \\ \dashrightarrow \: { \boxed{ \rm{ \: x = 2 \: }}}$

Answer: The number is 2
