Question

найти корень уравнения: х + x/11 = 24/11

Answer 1

x + x/11 = 24/11

11 * х + х/11 * 11 = 24/11 * 11;

11 * х + х = 24

х * (11 + 1) = 24;

х * 12 = 24

х = 24 : 12;

х = 2.

Ответ: 2.

Answer 2

$x + \frac{x}{11} = \frac{24}{11} \\ \frac{11x + x}{11} = \frac{24}{11} \\ \frac{12x}{11} = \frac{24}{11} \\ 12x = \frac{11 \times 24}{11} = 24 \\ x = 24 \div 12 = 2$
