Question

3x mas 1 sobre 2 igual a 6 (x mas 2)​

Answer 1

Respuesta:

$3x + \frac{1}{2} = 6(x + 2) \\ \\ 3x + \frac{1}{2} = 6x + 12 \\ \\ 3x - 6x = 12 - \frac{1}{2} \\ \\ - 3x = \frac{24 - 1}{2} \\ \\ - 3x = \frac{23}{2} \\ \\ x = \frac{23}{2} \div ( - 3) \\ \\ x = - \frac{23}{6} \\ comprobación \\ 3 \times ( - \frac{23}{6} ) + \frac{1}{2} = 6( - \frac{23}{6} + 2) \\ \\ - \frac{69}{6} + \frac{1}{2} = 6( \frac{ - 23 + 12}{6} ) \\ \\ - \frac{23}{2} + \frac{1}{2} = 6( - \frac{11}{6} ) \\ \\ - \frac{22}{2} = - \frac{66}{6} \\ \\ - 11 = - 11$
