x-100=100+200
\(\Rightarrow\)x-100=300
\(\Rightarrow\)x =300-100
\(\Rightarrow\)x =200
k cho minh nha
x - 100 = 100 + 200
x - 100 = 300
x = 300 + 100
x = 400
X - 100 = 100 + 200
X - 100 = 300
X = 300 - 100
X = 200
k nha ^_-
x - 100 = 100 + 200
x - 100 = 300
x = 300 + 100
x = 400
eoeo ong nào diên mà làm theo tui vạy eoeo
\(x-100=100+200\)
\(x-100=\)\(300\)
\(x\) \(=\)\(300-100\)
\(x\) \(=\)\(200\)
\(x-100=100+200\)
\(x-100=300\)
\(x=300+100\)
\(x=400\)
Ta có :
x - 100 = 100 + 200
x - 100 = 300
x = 300 + 100
x = 400
Vậy ....
