Respuesta:

24

Explicación paso a paso:


The equation is posed as values are indicated.


{[(x + 0,5) x 4] – 2} ÷ 2 = 48


It is cleared as follows:


{[(x + 0,5) x 4] – 2} = 48 x 2


{[(x + 0,5) x 4] – 2} = 96


[(x + 0,5) x 4] = 96 + 2


[(x + 0,5) x 4] = 98


[(x + 0,5)] = 98 ÷ 4


x + 0,5 = 24,5


x = 24,5 – 0,5 = 24


X = 24

The number that they sent  is : x = 24 .

  The number that they sent is calculated through the approach and solution of a first degree equation, whose incognita is the number x, as follows:

  [4*( x +0.5 ) -2 ]/2 = 48

    4*( x +0.5) - 2 = 96

         4*( x +0.5)  = 98

              x +0.5 = 98/4

              x + 0.5 = 24.5

                       x = 24.5 - 0.5

                       x = 24

  The solution of an equation is the value of the incognite (x) that meets equality.
