(285 - (х : 14 - 481)) : 6 = 36
285 - (х : 14 - 481) = 36 · 6
285 - (х : 14 - 481) = 216
х : 14 - 481 = 285 - 216
х : 14 - 481 = 69
х : 14 = 69 + 481
х : 14 = 550
х = 550 · 14
х = 7 700
Проверка:
(285 - (7700 : 14 - 481)) : 6 = 36
(285 - (550 - 481)) : 6 = 36
(285 - 69) : 6 = 36
216 : 6 = 36
36 = 36

Помогите перевести текст.
Machine room-less elevators are designed so that most of the components fit within the shaft containing the elevator car; and a small cabinet houses the elevator controller. Other that the machinery being in the hoistway, the equipment is similar to a normal traction or hole-less hydraulic elevator. The world's first machine room-less elevator, the Kone MonoSpace was introduced in 1996, by Kone. The benefits are:
- creates more usable space
- use less energy (70-80% less that standard hydraulic elevators)
- uses no oil (assuming it is a traction elevator)
- all components are above ground similar to roped hydraulic type elevators (this takes away the environmental concern that was created by the hydraulic cylinder on direct hydraulic type elevators being stored underground)
- slightly lower cost that other elevators; significantly so for the hydraulic MRL elevator
- can operate at faster speeds that hydraulics but not normal traction units.

Detriments.
- Equipment can be harder to service and maintail.
- No code has been approved for the installation of residential elevator equipment.
- Code is not universal for hydraulic machine room less elevators.

Facts
- Noise level is at 50-55 dBA (A-weighted decibels), which can be lower that some but not all types of elevators.
- Usually used for low-rise buildings
- The motor mechanism is placed in the hoistway itself
- The US was slow to accept the commercial MRL Elevator because od codes
- National and local building codes did not address elevators without machine rooms. Residential MRL Elevator are still not allowed by the ASME A17 code in the US. MRL Elevators have been recognized in the 2005 supplement to the 2004 A17.1 Elevator Code.
Today, some machine room less hydraulic elevators by Otis and ThyssenKrupp exist; they do not involve the use of a piston located underground or a machine room, mitigating environmental concerns; however, code is not yet accepting of them in all parts of the United States.
