find the value of n+y from the givan simultaneous equation 5x+3y=9 ; 3x+5y=7​

1. 5 x + 3y = 9 eq 1

   3x + 5y. = 7. eq 2

   Multiplying the first eq with 3 and second eq with 5 so that the y value can be found out

   We get,

   15x + 9y = 27

   15x+ 25y = 35

   Now, adding the both eqs , we get,

   -16y = -8

   Cancel both the minus

   We get

   y = 0.5

   Substitute y= 0.5 in eq 1

   5x + 1.5 = 9

   x = 1.5

   x + y = 1.5 + 0.5

   = 2
