Question

Найдите больший корень уравнения 3- х + 2x – 3, (3) = 2 3/4​

Answer 1

$3 - x + 2x - 3 \frac{1}{3} = 2 \frac{3}{4} \\ \\ 3 + x - \frac{10}{3} = \frac{11}{4} \\ \\ \frac{9 - 10}{3} + x = \frac{11}{4} \\ \\ - \frac{1}{3} + x = \frac{11}{4} \\ \\ x = \frac{11}{4} + \frac{1}{3} = \frac{33 + 4}{12} \\ \\ x = \frac{37}{12} = 3 \frac{1}{12} .$
