x + 80 = 1000
x = 1000 - 80
x = 920

2.Tìm x
x+80=100
x=100-80
x=20
800 - x = 200 + 100
800 - x = 200 + 100
800 -x = 300
x = 800 - 300
x = 500
100 + x = 200 + 800
100 + x = 200 + 800
100 + x = 1000
x = 1000 - 100
x = 900
kết bạn nhé
100 + x = 200 + 800
100 + x = 1000
x = 1000 - 100
x = 900
100 + x = 200 + 800
100 + x = 1000
x = 1000 - 100
x = 900
