Question

Решите уравнение (2 7/8-×)+4 1/6=5 3/4​

Answer 1

$(2 \frac{7}{8} - x) + 4 \frac{1}{6} = 5 \frac{3}{4} \\ \frac{23}{8} - x = \frac{23}{4} - \frac{25}{6} \\ \frac{69}{24} - x = \frac{138}{24} - \frac{125}{24} \\ \frac{69}{24} - x = \frac{13}{24} \\ - x = \frac{13}{24} - \frac{69}{24} \\ - x = - \frac{56}{24} \\ - x = - 2 \frac{8}{24} \\ x = 2 \frac{1}{3}$
