27,703 - х = 18,926х = 27,703 - 18,926х = 8,77727,703  - 8,777 = 18,92618,926=18,926(312,45 -0,00045)+х = 518,13955 - 5,69х= 518,13955 - 5,69 - (312,45 -0,00045)х = 518,13955 - 5,69 - 312,45 + 0,00045х = (518,13955 +0,00045)  - (312,45 + 5,69)х = 518,14 - 318,14х= 200(312,45 -0,00045) + 200 = 518,13955  - 5,69(312,45000  - 0,00045) + 200  = 518,13955 - 5,69000312,44955 +200,00000 = 512,44955512,44955= 512,44955...
