1+1: (1+1: (1+1 / (x+2017))) = 1+1: (1+1: (x+2017) / (x+2013))) = 1+1: (1 + (x+2013) / (x+2014)) =

=1+1: (2x+4027) / (x+2014) = 1 + (x+2014) / (2x+4027) = 1,44

(x+2014) / (2x+4027) = 0,44

0,88x+1771,88=x+2014

x-0,88x=1771,88-2014

0,12x=-242,12

x=-242,12:0,12

x=-2017 2/3

1+1: (1+1: (1+1: (х+2013))) = (1,2) ^2

1: (1+1: (1+1: (х+2013))) = (1,2) ^2-1

(1+1: (1+1: (х+2013)) = 1 / ((1,2) ^2-1)

1: (1+1: (х+2013) = 1 / ((1,2) ^2-1) - 1

1+1: (х+2013) = 1 / (1 / ((1,2) ^2-1) - 1)

1: (х+2013) = 1 / (1 / ((1,2) ^2-1) - 1) - 1

х+2013=1 / (1 / (1 / ((1,2) ^2-1) - 1) - 1)

x=1 / (1 / (1 / ((1,2) ^2-1) - 1) - 1) - 2013 = - 2017, (6)
