200 + 400 ( X : 30 ) = 200
400 ( X : 30 ) = 200 - 200
400 ( X : 30 ) = 0
X : 30 = 0 : 400
X : 30 = 0
X = 0 x 30
X = 0
200 + 400(X : 30) = 200
400(X : 30) = 200 - 200
400(X : 30) = 0
X : 30 = 0 : 400
X : 30 = 0
X = 0 x 30
X = 0
Vậy X = 0
Ủng hộ ☆☆☆☆☆ nha mấy bn
200 + 400 ( x : 30 ) = 200
400 ( x : 20 ) = 200 - 200
400 ( x : 30 ) = 0
X : 30 = 0 : 400
X : 30 = 0
X = 0 x 30
X = 0
200 + 400 (X:30) = 200
400 (X:30) = 200-200
400 (X:30) = 0
X : 30 = 0 : 400
X : 30 = 0
X = 0 * 30
X = 0
Ta có: 200 + 400 . ( x : 30 ) = 200
400 ( x : 30 ) = 0
X : 30 = 0
X = 0
Ta có: 200 + 400 . ( x : 30 ) = 200
400 ( x : 30 ) = 0
X : 30 = 0
X = 0
