2x + 100= 200 + 100
2x + 100 = 300
2x = 300 - 100
2x = 200
x = 100
Vậy x = 100
2x + 100 = 200 + 100
2x + 100 = 300
2x = 300 - 100
2x = 200
x = 100
2x+100=200+100
2x+100=300
2x= 300-100
2x=200
x= 200:2
x= 100
tk nhé
2x + 100 = 200 + 100
2x + 100 = 300
2x = 300 - 100
2x = 200
x = 200 : 2
x = 100
Chúc bn học tốt ^_^
2x+100=200+100 2x+100=300 x= 300-100=200 x=200
\(2x+100=200+100\)
\(2x+100=300\)
\(2x=300-100\)
\(2x=200\)
\(x=200:2\)
\(\Rightarrow x=100\)
2x + 100 = 200 + 100
2x +100 = 300
2x = 300 - 100
2x = 200
x = 200 : 2
x = 100
2x + 100 = 200 + 100
2x +100 = 300
2x = 300 - 100
2x = 200
x = 200 : 2
x = 100
