Question

Решите уравнение
2 1/4 - 1 1/3x = 1 5/51

Answer 1

Ответ:

$\frac{235}{272}$

Пошаговое объяснение:

$2\frac{1}{4} - 1\frac{1}{3}x = 1\frac{5}{51}\\ \\1\frac{1}{3}x = 2\frac{1}{4} - 1\frac{5}{51} = \frac{9}{4} - \frac{56}{51} = \frac{459-224}{204} = \frac{235}{204}\\\\x = \frac{235}{204} : \frac{4}{3} = \frac{235*3}{204*4} = \frac{235}{68*4} = \frac{235}{272}$
