x + 600 = 1400 - 600
x + 600 = 800
x = 800 - 600
x = 200
K mk nha
x+600=1400-600
x+600=800
x. =800-600
x. =200
k mình nha!
\(x+600=1400-600\)
\(x+600=800\)
\(x=800-600\)
\(x=200\)
Vậy \(x=200\)
\(x+600=1400-600\)
\(\Leftrightarrow x+600=800\)
\(\Leftrightarrow x=200\)
x + 600 = 800
x = 800 - 600
x = 200
vậy x = 200
x + 600 = 1400 - 600
x + 600 = 800
x = 800 - 600
x = 200
x+600=1400-600
x+600=800
x=800-600
x=200
X + 600 = 1400 - 600
X + 600 = 800
X = 800 - 600
X = 200
x + 600 = 1400 - 600
x + 600 = 800
x = 800 - 600
x = 200
Vậy x = 200
x + 600 = 800
x = 800 - 600
x = 200
x+ 600 = 1400 - 600
=> x+ 600 = 800
=> x= 200
đáp số x= 200
