Explicación paso a paso:
[tex] \frac{9x}{7} + \frac{5x}{7} + 9 = 27 \\ \\ \frac{14x}{7} + 9 = 27 \\ \\ \frac{14x}{7} = 27 - 9 \\ \\ \frac{14x}{7} = 18 \\ \\ 14x = 18 \times 7 \\ \\ 14x = 126 \\ \\ x = 126 \div14 \\ \\ x = 9[/tex]
[tex]\frac{9x}{7} +\frac{5x}{7} +9=27\\\\\frac{9x+5x}{7} =27-9\\\\\frac{14x}{7} =18\\\\14x=7*18\\\\14x=126\\\\x=9[/tex]
