x + 34 = 56
x = 56 - 34
x = 22
x + 67 = 89
x = 89 - 67
x = 22
x+34=56
x =56-34
x=22
x+67=89
x =89-67
x =22
X+34=56 x+67=89
x=56-34 x=89-67
x=22 x=22
\(X+34=56\)
\(X\) \(=56-34\)
\(X\) \(=22\)
\(X+67=89\)
\(X\) \(=89-67\)
\(X\) \(=22\)
x+34=56 x+67=89
x =56-34 x =89-67
x = 22 x =22
Vậy x=22 Vậy x=22
ai k mik mik k lại nha
