Step-by-step explanation:
2x +3y -8 =0
3x +y -5 =0
2x +3y = 8 ------<1>
3x + y = 5 -------<2> × 3
This done to make the coefficient same for any one of the variables
2x +3y =8--------<1>
9x +3y = 15 -------<2>
<2> - <1>
9x +3y =15. --
2x +3y =8
change the symbols ,,,
so we get ,,
9x +3y =15
-2x -3y = -8. +
now add them ,,
7x = 7
=> [ x = 7/7 = 1 ] <=
Now substitute x= 1 in any of the equations ,,
3x +y =5
3(1) +y =5
3 + y =5
=> [ y = 5 - 3 = 2 ] <=
hope it helps you
