a )
\(y+34=95-12\)
\(\Rightarrow y+34=83\)
\(\Rightarrow y=83-34\)
\(\Rightarrow y=49\)
Vậy \(y=49\)
b )
\(y\times3=9\)
\(\Rightarrow y=9:3\)
\(\Rightarrow y=3\)
Vậy \(y=3\)

chúc bạn học tốt
a, y + 34= 95-12
y + 34 = 83
y = 83 - 34
y =49
b, y x 3 =9
y= 9:3
y = 3
a) \(y+34=95-12\)
\(\Rightarrow y+34=83\)
\(\Rightarrow y=83-34\)
\(\Rightarrow y=49\)
Vậy : \(y=49\)
b) \(y.3=9\)
\(\Rightarrow y=9:3\)
\(\Rightarrow y=3\)
Vậy : \(y=3\)

Hc tốt #
y + 34 = 95 - 12
y + 34 = 83
y = 83 - 34
y = 49.
