x : 10 x 100 = 1000 + 100
x : 10 x 100 = 1100
x : 10 = 1100 : 100
x : 10 = 11
x = 11 x 10
x = 110
x : 10 x 100 = 1000 + 100
x : 10 x 100 = 1100
x : 10 = 1100 : 100
x : 10 = 11
x = 11 x 10
x = 110
x:10x100=1000+100
x:10x100=1100
x:10 =1100:100
x:10 =11
x =11x10
x =110
x : 10 x 100 = 1000 + 100
=>x:10x100=1100
=>x:10=1100:100
=>x:10=11
=>x=11x10
=>x=110
Vậy x=110.Nha
