55 - y + 33 = 76
55 - y = 76 - 33
55 - y = 43
y = 55 - 43
y= 12
Vậy y =12
55 - y + 33 = 76
55 - y = 76 - 33 = 43
y = 55 - 43
y = 12
55-y+33=76
55-y=76-33
55-y=43
y=55-43
y=12
Vậy:y=12
55 - y + 33 = 76
55 - y = 76 - 33
55 - y = 43
y = 55 - 43
y = 12
y : 55 - y + 33 = 76
y : ( 55 - 33 ) = 76
y : 22 = 76
y = 76 x 22
y = 1672
55 - y = 76 - 33
55 - y = 43
y = 55 - 43
y = 12
\(55-y+33=76\)
\(\Rightarrow55-y=76-33\)
\(\Rightarrow55-y=43\)
\(\Rightarrow y=55-43\)
\(\Rightarrow y=12\)
Vậy y = 12
