\(x+900=9000-900\)
\(x+900=8100\)
\(x=8100-900\)
\(x=7200\)
Vậy \(x=7200\)
\(x+900=9000-900\)
\(x+900=8100\)
\(x=8100-900\)
\(x=7200\)
x + 900 = 9000 - 900
x + 900 = 8100
x = 8100 - 900
x = 7200
~~ tk mk nha ~~ ^^
Ai tk mk mk tk lại ~~ ^_^
Kb vs mk nha m.n ~~ n_n
bạn ơi bằng7200 nhé k cho mình nha
X+900=9000-900
X+900=8100
X=8100-900
X=7200
X + 900 = 9000 - 900
X + 900= 8100
X = 8100 - 900
X = 7200
X + 900 = 9000 - 900
X + 900 = 8100
X = 8100 + 900
X = 9000
X + 900 = 9000 - 900
X + 900 = 8100
X = 8100 + 900
X = 9000
X + 900 = 9000 - 900
X + 900 = 8100
X = 8100 + 900
