Explicación paso a paso:
-------------------------------------------------------------------------------------------------------------
-El numero será X
x / 2 + 2x + 3x = 55
5x + x / 2 = 55
10x + x= 55 . 2
11x = 110
x = 110 / 11
x = 10
-------------------------------------------------------------------------------------------------------------
RPT: El numero es el 10
-------------------------------------------------------------------------------------------------------------
Comprobación:
( x / 2 ) + 2x + 3x = 55
( 10 / 2 ) + 2 ( 10 ) + 3 ( 10 ) = 55
5 + 20 + 30 = 55
55 = 55
