Question

(x-1 8/9) + 3 17/19 = 4 14/19​

Answer 1

Пошаговое объяснение:

$(x - 1\frac{8}{9} ) + 3 \frac{17}{19} = 4 \frac{14}{19} \\ (x - \frac{17}{9}) + \frac{74}{19} = \frac{90}{19} \\ x - \frac{17}{9}+ \frac{74}{19} = \frac{90}{19} \\ x + \frac{343}{171} = \frac{90}{19} \\ x = \frac{90}{19} - \frac{343}{171} \\ x = \frac{467}{171}$
