Question

розв'язати рівняння 5/24 x+ 7 2/3 = 11 5/8

Answer 1

Ответ:

$\frac{5}{24} x + 7 \frac{2}{3} = 11 \frac{5}{8} \\ \frac{5}{24} x = 11 \frac{5}{8} - 7 \frac{2}{3} \\ \frac{5}{24} x = 11 \frac{15}{24} - 7 \frac{16}{24} \\ \frac{5}{24} x = 10 \frac{39}{24} - 7 \frac{16}{24}$

$\frac{5}{24} x = 3 \frac{23}{24} \\ x = 3 \frac{23}{24} \div \frac{5}{24} \\ x = \frac{95}{24} \times \frac{24}{5} \\ x = 19$
