1000+1000+1000+x=4000
3000+x=4000
x=4000-3000
x=1000
mình mình tk lại
1000 +1000+1000+x=4000
=> x=4000-1000-1000-1000
=>x= 1000
3000 + X = 4000
X = 4000 - 3000
X = 1000
ai tk minh thi minh tk lai
cam on
1000 + 1000 + 1000 + X = 4000
X= 4000 - 3000
X = 1000
1000 + 1000 + 1000 = 3000
do la li do co 3000
k nhe ban
1000 + 1000 + 1000 + x = 4000
x = 4000 - 3000
x = 1000
k nhe
X = 4000 - 3000
=> X = 1000
Vậy X = 1000
