Question

Рівняння 6(5/6х-1 2/3)=17

Answer 1

Пошаговое объяснение:

$6( \frac{5}{6} x - 1 \frac{2}{3} ) = 17 \\ \frac{5}{6} x - \frac{1 \times 3 + 2}{3} = \frac{17}{6} \\ 5x - 2(3 + 2) = 17 \\ 5x - 2 \times 5 = 17 \\ 5x - 10 = 17 \\ 5x = 17 + 10 \\ 5x = 27 \\ x = \frac{27}{5} = 5 \frac{2}{5 } = 5.4$
