Question

{84,4+[5,18-(6,24×x+18,18):9,7]:10,9}:141= 0,6

Answer 1

{84,4+[5,18-(6,24×x+18,18):9,7]:10,9}= 0,6x141
84,4+[5,18-(6,24×x+18,18):9,7]:10,9= 84,6
[5,18-(6,24×x+18,18):9,7]:10,9=84,6-84,2
[5,18-(6,24×x+18,18):9,7]:10,9=0,4
5,18-(6,24×x+18,18):9,7=0,4x10,9
5,18-(6,24×x+18,18):9,7=4,36
(6,24×x+18,18):9,7=5,18-4,36
(6,24×x+18,18):9,7=0,82
(6,24×x+18,18)=0,82x9,7
(6,24×x+18,18)=7,954
6,24x=7,954-18,18
6,24x=-10,226
x=-1,63
