Ответ:

х= -4/11.

Объяснение:

Решить уравнение:

-36(6х+1)=9(4-2х)

Раскрыть скобки:

-216х-36=36-18х

Привести подобные члены:

-216х+18х=36+36

-198х=72

х=72/-198

х= -36/99 = -4/11.

Проверка путём подстановки вычисленного значения х в уравнение показала, что данное решение удовлетворяет данному уравнению.

The Tom Thumb


1 The early locomotives were small and slow and they
were not powerful. Besides, the rails on which they ran broke very often.
So many people did not take them
seriously.


2 But in
1830. Peter Cooper, an American, constructed a steam loco which could develop a
higher speed than the other engine. The locomotive was so small and light that
his inventor called it the Tom Thumb.


3. The
first run of the Tom Thumb was quite successful. The locomotive travelled
a15-mile distance in one hour and 12 minutes to the delight of its inventor and
36 passengers.But the end of the travel was not so happy as the beginning.


4. On the
way back the inventor wanted to show that his loco could run much quicker than
a carriage drawn by a horse. The Tom Thumb ran so fast that soon it was really
ahead.of the carriage. Suddenly, something broke in the engine and the
locomotive slowed down.The horse ran fast with the passengers looking
triumphant and happy.
