x + 300 = 600 + 500
x + 300 = 1100
x = 1100 - 300
x = 800
x + 300 = 600 + 500
x + 300 = 1100
x = 1100 - 300
x = 800
X + 300 = 600 + 500
X + 300 = 1100
X = 1100 - 300
X = 800 k mk nha mọi người
x + 300 = 600 + 500
x + 300 = 1100
x = 1100-300
x = 800
k mik nếu đúng nhe
x+300=600+500
x+300=1100
x=1100-300
x=800
Vay x=800
x + 300 = 600 + 500
x + 300 = 1100
x = 1100 - 300
x = 800
Vậy x = 800
x + 300 = 600 + 500
x + 300 = 1100
=> x = 1100 - 300
x = 800
x+300=600+500
x+300=1100
x=1100-300
x=800
