1) 5 x + 8 = 9 ,
2) 2 X + 3 y =4
In the first equation,
5x=9 - 8
therefore x = 1/5.
In second equation ,
Putting value of x in it
(2×1/5) +3y = 4,
2/5+3y = 4,
taking LCM of 2/5+3y
2+15y/5 = 4,
2+15y = 20,
15y =20 -2
therefore y = 18/15
Y = 6/5
Therefore x + y = (1/5) + (6/5)
Therefore x + y = 7/5 = 1.4
