Question

d-m=5 140d+134m=136,4​

Answer 1

$d-m=5140d+134m=136,4$

$\left \{ {{-5140d+5140m=-701096} \atop {5140d+134m=136,4}} \right.$

$\left \{ {{d-m=136,4} \atop {5140d+134m=136,4}} \right.$

$5274m=-700959,6$

$m=-\frac{194711}{1465}$

$d-(-\frac{194711}{1465} )=134,4$

$d=\frac{1023}{293}$

$(d,m)=(\frac{1023}{293} ,-\frac{194711}{1465} )$

$\frac{1023}{293} -(-\frac{194711}{1465} )=5140*\frac{1023}{293} +134(-\frac{194711}{1465} )=136,4$

$\frac{682}{5} =\frac{682}{5} =\frac{682}{5}$

$(d,m)=(\frac{1023}{293} ,-\frac{194711}{1465} )$
