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

TÌM Y BIẾT:42+Y/76=153/171
42+y /76=153/171
42+y/76=153/171
42+y/76=153/171
y/76=153/171-42
y/76=-781/19
y=-781/19*76
y=-3124
Tìm y, biết: \(\frac{42+y}{76}=\frac{153}{171}\)
\(\frac{42+y}{72}=\frac{153}{171}\)
\(\Rightarrow\left(42+y\right)\times171=76\times153\)
\(\Rightarrow\left(42+y\right)\times171=11628\)
\(\Rightarrow42+y=11628:171=68\)
\(\Rightarrow y=68-42=26\)
\(\frac{42+y}{76}=\frac{153}{171}\Rightarrow171\left(42+y\right)=153.76\Rightarrow7182+171y=11628\Rightarrow171y=4446\Rightarrow y=26\)
Vậy y = 26
\(\frac{42+y}{76}=\frac{153}{171}\)
\(\left(42+y\right).171=153.76\)
\(\left(42+y\right).171=11628\)
\(42+y=11628:171\)
\(42+y=68\)
\(y=68-42\)
\(y=26\)

Tìm y, biết: 42 + y / 76 = 153 / 171 . tick mink tick lại, nhớ giải đầy đủ nhé
\(\frac{42+y}{76}=\frac{153}{171}\)
\(\left(42+y\right):76=\frac{153}{171}\)
\(42+y=\frac{153}{171}\text{×}76\)
\(42+y=68\)
\(\Rightarrow y=68-42\)
\(\Rightarrow y=26\)
\(\frac{42+y}{76}=\frac{153}{171}\)
\(\left(42+y\right):76=\frac{153}{171}\)
\(42+y=\frac{153}{171}\text{×}76\)
\(42+y=68\)
\(\Rightarrow y=68-42\)
\(\Rightarrow y=26\)
42 + y / 76 = 153 / 171
/ <~ Là phần ds mấy bạn
42 + y/76 = 153/171
y/76=153/171 - 42
y/76 = 781/19
y = 3124
42+y/76 = 153/171
Tim y
Ai lam nhanh nhat , dung nhat minh tick cho . Huaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa do .
42 + y/76 = 153/171
y/76 = 153/171 - 42
y/76 = 781/19
y = 3124
\(42+\frac{y}{76}=\frac{153}{171}\)
\(y:76=\frac{153}{171}-42\)
\(y:76=-\frac{781}{19}\)
\(y=-\frac{781}{19}\times76\)
\(y=-3124\)
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?
\(42+\frac{y}{76}=\frac{153}{171}\)
\(\frac{42}{1}+\frac{y}{76}=\frac{153}{171}\)
\(\frac{y}{76}=\frac{153}{171}-\frac{42}{1}\)
\(\frac{y}{76}=\frac{-781}{19}\)
\(\Rightarrow y=\frac{-781.76}{19}=-3124\)
