Реши уравнения 900-x=90 x+1020=3010 360: x=60 x-740=10074 x: 60=50 x*200=1800

Answer 1

900-x=90
-x=-810
x=810

x+1020=3010
x=1990

360:x=60
x=360:60
x=6

x-740=10074
x=10814

x:60=50
x=50×60
x=3000

x×200=1800
x=1800:200
x=9

Answer 2

900-х=90
Х=900-90
Х=810

Х+1020=3010
Х=3010-1020
Х=1990

360:х=60
Х=360:60
Х=6

Х-740=10074
Х=740+10074
Х=10814

Х:60=50
Х=60×50
Х=3000

Х×200=1800
