\(42+\frac{y}{76}=\frac{153}{171}\)
\(y:76=\frac{153}{171}-42\)
\(y:76=-\frac{781}{19}\)
\(y=-\frac{781}{19}\times76\)
\(y=-3124\)

Tìm y, biết: \(\frac{42+y}{76}=\frac{153}{171}\)
\(\frac{42+y}{72}=\frac{153}{171}\)
\(\Rightarrow\left(42+y\right)\times171=76\times153\)
\(\Rightarrow\left(42+y\right)\times171=11628\)
\(\Rightarrow42+y=11628:171=68\)
\(\Rightarrow y=68-42=26\)

Tìm x,y biết : (x-y).(x+y)=226
giải giúp mk với (lời giải đầy đủ nhé)
ai tick cho 1 tick
Có ai làm giúp mình bài toán này nhé
Có bạn nào có cách giải ko
Sau đây là bài toán
42+y/76=153/171
\(42+\frac{y}{76}=\frac{153}{171}\)
\(42+\frac{y}{76}=\frac{17}{19}\)
\(\frac{y}{76}=\frac{17}{19}-42\)(Chỗ này bạn tự quy đồng)
\(\frac{y}{76}=-\frac{781}{19}\)
\(\Rightarrow y=-781\times76:19=-3124\)
Bạn chưa học âm đâu?

\(42+\frac{y}{76}=\frac{153}{171}\)
\(\frac{42}{1}+\frac{y}{76}=\frac{153}{171}\)
\(\frac{y}{76}=\frac{153}{171}-\frac{42}{1}\)
\(\frac{y}{76}=\frac{-781}{19}\)
\(\Rightarrow y=\frac{-781.76}{19}=-3124\)

42+y phan 76=153 phan 171 [tim x]
\(\frac{42+y}{76}=\frac{153}{171}=\frac{17}{19}\)
\(\Rightarrow\left(42+y\right)\times19=76\times17\)
\(\left(42+y\right)\times19=1292\)
\(42+y=1292:19\)
\(42+y=68\)
\(y=68-42\)
\(y=26\)
