nho k cho minh nha ban
X x 100 + X x 200 + X x 300 + X x 400 + X x 500 + X x 512 = 2012
mk đang cần gấp lắm ai đúng mk tick
X x 100 + X x 200 + X x 300 + X x 400 + X x 500 + X x 512 = 2012
X = 2012 : ( 100 + 200 + 300 + 400 + 500 + 512)
X = 2012 : 2012
X = 1
Nhớ k mình nhé
X x 100 + X x 200 + X x 300 + X x 400 + X x 500 + X x 512 = 2012
X x ( 100 + 200 + 300 + 400 + 500 + 512 ) = 2012
X x 2012 = 2012
X = 2012 : 2012
X = 1

ai tick mk rùi mk tick lại
x + 200 = 500 + 200
x + 200 = 700
x = 700 - 200
x = 500
Thử lại : 500 + 200 = 700
500 + 200 = 700
Vậy 700 = 700
