Answer 1

1)(19×700)÷70+850+x / 18=6000÷50;
13300/70+850+ х/18 =120;
190+850+ х/18=120;
1040+ х/18 =120;
18720+х=2160;
х=2160-18720;
х=-16560.
2)2×( x×5)×16/74+68-92÷4=500000012-49998435;
2*(5х)*16/74+68-23=450001577;
(2*(5х)*16)/74+68-23=450001577;
(5х*16)/37+68-23=450001577;
80х/37+68-23=45001577;
80х/37+45=450001577;
80х+1665=16650058349;
80х=16650058349-1665;
80х=16650056684;
х=4162514171/20.
