Ta có
y - 4873 = (350 - 350) : 25 + 27
y - 4873 = 0 : 25 + 27
y - 4873 = 0 + 27
y - 4873 = 27
y = 27 + 4873
y = 4900
Hết vội chưa :)
y - 4873 = ( 175 x 2 - 50 x 7 ) : 25 + 27
y = ( 350 - 350 ) : 25 + 27 + 4873
y = 0 + 27 + 4873
y = 4900
\(y-4873=\left(175\times2-50\times7\right):25+27\)
\(\Rightarrow y-4873=\left(350-350\right):25+27\)
\(\Rightarrow y-4873=0:25+27\)
\(\Rightarrow y-4873=27\)
\(\Rightarrow y=27+4873\)
\(\Rightarrow y=4900\)
y-4873=(350-350):25+27
y-4873=0:25+27
y-4873=0+27
y =27+4873
y =4900
\(y-4873=\left(175\cdot2-50\cdot7\right):25+27\)
\(y-4873=\left(350-350\right):25+27\)
\(y-4873=0:25+27\)
\(y-4873=0+27\)
\(y-4873=27\)
\(y=27+4873\)
\(y=4900\)
y - 4873 = ( 175 x 2 - 50 x 7 ) : 25 + 27
y = ( 350 - 350 ) : 25 + 27 + 4873
y = 0 + 27 + 4873
y = 4900
hok tốt
