x - 300 = 400 - 100 - 100
x - 300 = 200
x = 200 + 300
x = 500.
x - 300 = 400 - 100 - 100
x - 300 = 300 - 100
x - 300 = 200
x = 200 + 300
x = 500
x - 300 = 400 - 100 - 100
x - 300 = 300 - 100
x - 300 = 200
x = 200 + 300
x = 500
x-300=400-100-100
x-300=300-100
x-300=200
x=200+300
x=500
ai k mk rùi mk sẽ k lại
x-300=400-100-100
x-300=300-100
x-300=200
x=200+300
x=500
Vậy x=500
x-300=400-100-100
x-300=200
x=200+300
x=500
x - 300 = 400 - 100 - 100
x - 300 = 300 - 100
x - 300 = 200
x = 200 + 300
x = 500
k mk nha
