1000 + x = 900 + 300
x = 900 + 300 - 100
x = 200
1000 + x = 900 + 300
1000 + x = 1200
x = 1200 - 1000
x = 200
\(1000+x=900+300\)
\(1000+x=1200\)
\(x=1200-1000\)
\(x=200\)
1000 nhân x = 1200. X = 1200 trừ 1000 =200
1000 + x = 900 + 300
1000 + x = 1200
x = 1200 - 1000
x = 200
1000+x=900+300
1000+x=1200
x=1200-1000
x=200
mik k bạn rùi nha!
1000 + x = 900 + 300
1000 + x = 1200
x = 1200 - 1000
x = 200
1000 + x = 900 + 300
1000 + x = 1200
x = 1200 - 1000
x = 200
1000 + x = 900 + 300
1000 + x = 1200
x = 1200 - 1000
x = 200
