Question

Решите уравнение:
5/12 х + 1,3 = 7/8 х + 0, 53

Answer 1

Ответ:

$\frac{5}{12} x + 1.3 = \frac{7}{8} x + 0.53 \\ \frac{5}{12} x - \frac{7}{8} x = 0.53 - 1.3 \\ \frac{10}{24} x - \frac{21}{24} x = - 0.77 \\ - \frac{11}{24} x = - 0.77 \\ x = \frac{77}{100} \times \frac{24}{11} \\ x = \frac{42}{25}$
