x + 300 = 700 - 25
x + 300 = 675
x = 675 - 300
x = 375
x + 300 = 700 - 25
x + 300 = 675
x = 675 - 300
x = 375
X + 300 = 700 - 25
X + 300 = 675
X = 675 - 300
X = 375
x + 300 = 700 - 25
x + 300 = 675
x = 675 - 300
x = 375
x + 300 = 700 - 25
x + 300 = 675
x = 675 - 300
x = 375
Vậy x = 375
x + 300 = 700 - 25
x + 300 = 675
x = 675 - 300
x = 375
