Question

Решить пропорции
11/x-2= 22/4
x- x/12 = - 55/12

Answer 1

$1) \: \frac{11}{x - 2} = \frac{22}{4} \\ \frac{11}{x - 2} = \frac{11}{2} \\ 11(x - 2) = 22 \\ 11x - 22 = 22 \\ 11x = 44 \\ x = 4 \\ 2) \: x - \frac{x}{12} = - \frac{55}{12} \\ \frac{12x - x}{12} = - \frac{55}{12} \\ 11x = - 55 \\ x = - 5$
