x + 100 = 300 - 100
x + 100 = 200
x = 200 - 100
x = 100
x + 100 = 300 - 100
x + 100 = 200
x = 200 - 100
x = 100
x + 100 = 300 - 100
x + 100 = 200
x = 200 - 100
x = 100
Vậy x = 100
K mk nha
Mk k lại
X+100=300-100
X+100=200
X =200-100
X =100
VẬY , X =100
x + 100 = 300 - 100
=> x + 100 = 200
=> x = 200 - 100
=> x = 100
Vậy x = 100
x+ 100 = 300-200
=> x+ 100 = 200
=> x= 200-100
=> x= 100
ta có : x+100=300-100
x+100=200
x =200-100
x =100
Vậy x = 100
x + 100 = 300 - 100
x + 100 = 200
x = 200 - 100
x = 100 k cho mình nhé mí bạn
x+100=300-100
x+100=200
x=200-100
x=100
K chị rùi
k lại nha
