900 + 100 + 200 - 200 + 14 x 2
= 900 + 100 + 200 - 200 + 28
= 2028
12 x 3 = 36
k mk nhé bn iu ^_-
900 + 100 + 200 - 200 + 14 x 2
= 900 + 100 + 200 - 200 + 28
= 900 + 100 + 0 + 28
= 1000 + 28
= 1028

k mk nha
thank you
X= 100 nha
k mk nha
mk k lại cho!
900 + 100 + x = 900 + 200
1000 + x = 1100
x = 1100 - 1000
x = 100
