100 – X.2 = 50 X.2 = 100 – 50 X.2 = 50 X = 50:2 = 25 b) 90 : X = 20 + 10 = 30 X = 90 : 30 = 3 Trả lời
a) 100 – X.2 = 50 X.2 = 100 – 50 X.2 = 50 X = 50:2 = 25 b) 90 : X = 20 + 10 = 30 X = 90 : 30 = 3 – VOTE 5 Sao giùm Trả lời
100 – X.2 = 50
X.2 = 100 – 50
X.2 = 50
X = 50:2 = 25
b) 90 : X = 20 + 10 = 30
X = 90 : 30 = 3
a) 100 – X.2 = 50
X.2 = 100 – 50
X.2 = 50
X = 50:2 = 25
b) 90 : X = 20 + 10 = 30
X = 90 : 30 = 3
