tk nha
\(x=6100\)
tk mình nha các bạn
Năn nỉ đó
9000 + 1000 - x = 3900
10000 - x = 3900
x = 10000- 3900
x = 6100
Vậy x = 6100
Nhớ bấm đúng cho mk nha!
x + 1000 = 9000
tìm x
x + 1000 = 9000
x = 9000- 1000
x = 8000
x + 1000 = 9000
x = 9000 - 1000
x = 8000
ai k mình thì mình k lại cho
x + 500 + 200 = 9000 - 1000
x+500+200=9000-1000
x+(500+200)=8000

k mình nha
