2x + 7 = 27/2
4x + 14 = 27
4x = 27 - 14
4x = 13
X = 13/4
El numero es 13/4
Respuesta:
13/4
Explicación paso a paso:
[tex]2x + 7 = \frac{27}{2} \\ \\ 2x = \frac{27}{2} - 7 \\ \\ 2x = \frac{27}{2} - \frac{14}{2 } \\ x = \frac{ \frac{27 - 14}{2} }{2} = [/tex]
[tex]x = \frac{ \frac{ \frac{13}{2} }{2} }{1} = \\ \frac{13}{2} \times \frac{1}{2 } = \frac{13}{4} [/tex]
[tex]2 \times \frac{13}{4} + 7 = \frac{26}{14} + \frac{14}{2} = \frac{26}{4} + \frac{28}{4} = \frac{54}{4 } = \frac{27}{2} [/tex]
