4x+3y=13

Por favor

Answer 1

6x-5y=9     ...... I    (3)
4x+3y=13  .....  II   (5)

18x - 15y = 27
20x+15y = 65
'''''''''''''''''''''''''''''''''''''
38x = 92
  x = 92/38
  x = 46/19  .... III

III en I

6x-5y= 9
$6( \frac{46}{19} )-5y = 9$
$\frac{46}{19}- 9= 5y$
$\frac{414-9}{19} = 5y$
$\frac{405}{19} = 5y$
$\frac{405}{19.5} = y$

$\frac{81}{9} = y$

CS= (46/19; 81/9)
