Ta có :
250 * y + 750 * y = 1001 * 2345 - 2345
=> ( 250 + 750 ) * y = ( 1001 - 1 ) * 2345
=> 1000 * y = 1000 * 2345
=> y = 2345
Vậy y = 2345
\(yx\left(250+750\right)=2347345-2345\)
\(yx1000=2345000\)
\(y=2345000:1000\)
\(y=2345\)
\(250\times y+750\times y=1001\times2345-2345\)
\(\Rightarrow\)\(y\times\left(250+750\right)=2345\times\left(1001-1\right)\)
\(\Rightarrow\)\(y\times1000=2345\times1000\)
\(\Rightarrow\)\(y\times1000=2345000\)
\(\Rightarrow\)\(y=2345000\div1000\)
\(\Rightarrow\)\(y=2345\)
250 x y + 750 x y = 2347345 - 2345
250 x y + 750 x y = 2345000
y x ( 250 + 750) = 2345000
y x 1000 =2345000
y =2345000 : 1000
y = 2345
250 x y + 750 x y = 1001 x 2345 - 2345
250 x y + 750 x y = 2 345 000
y x ( 250 + 750 ) = 2 345 000
y x 1000 = 2 345 000
y = 2 345 000 : 1000
y = 2345 .
