x + 100 - 200 = 500 x 2 + 100
x + 100 - 200 = 1100
x + 100 = 1100 + 200
x + 100 = 1300
x = 1300 - 100
x = 1200 k mk,mk sẽ k lại bn
x+100-200=500x2+100
x+100-200=1000+100
x+100-200=1100
x+100 =1300
x =1200
vậy x=1200.
\(x+100-200=500\times2+100\)
\(x-100=1000+100\)
\(x-100=1100\)
\(x=1100+100\)
\(x=1200\)
x + 100 - 200 = 500 x 2 + 100
x + 100 - 200 = 1000 + 100
x + 100 - 200 = 1100
x + 100 = 1100 + 200
x + 100 = 1300
x = 1300 - 100
x = 1200
x+100-200=1100
x+100=1100+200
x=100=1300
x=1300-100
x=1200
k đi nào!!
x+100-200=1000+100
x+100-200=1100
x+100=1100+200
x+100=1300
x=1300-100
x=1200
x + 100 - 200 = 500 x 2 + 100
x + ( - 100 ) = 1100
x = 1100 + 100
x = 1200
x + 100 - 200 = 500 x 2 + 100
x + 100 - 200 =1000 + 100
x + 100 - 200 = 1100
x + 100 = 1100 + 200
x + 100 = 1300
x = 1300 - 100
x = 1200
