Question

Решите уравнение
11/18х-2/9=5/12х+4/3

Answer 1

Ответ:

х = 8

Пошаговое объяснение:

$\frac{11}{18} x - \frac{2}{9} = \frac{5}{12} x + \frac{4}{3} \\ \frac{11}{18} x - \frac{5}{12} x = \frac{4}{3} + \frac{2}{9} \\ \frac{22 - 15}{36} x = \frac{12 + 2}{9} \\ \frac{7}{36} x = \frac{14}{9} \\ x = \frac{14}{9} \div \frac{7}{36} = \frac{14 \times 36}{9 \times 7} = \frac{2 \times 4}{1} \\ x = 8$
