Математика: 1+1: (1+1: (1+1: (x+=(1,2)² заранее

1) 1+1:(х+2013)= 1+   1    = х+2013 +1 = х+2014
(х+2013) (х+2013) (х+2013)

2) 1+ 1 = 1+ 1/
1+ 1 : х+2014 х+2014+х+2013 = 1+ 1/ 2х+4027 =
(х+2013) х+2014 х+2014

=1+ х+2014 =2х+4027+х+2014 = 3х+6041
  2х+4027 2х+4027 2х+4027

3) 3х+6041 =1,44
  2х+4027
3х+6041=1,44(2х+4027)
3х+6041=2,88х+5798,88
3х-2,88х=5798,88-601
0,12х= -242,12
х= -242,12 : 0,12 = -2017, 6667
