Answer:
2
explanation :
3x+5y=9-----(1)
5x+3y=7-----(2)
multiplying eq(1) by 5 & eq(2) by 3 we get
15x+25y=45
-15x ± 9y= - 21
_____________
16y=24
[tex]y = \frac{24}{16} = \frac{3}{2} [/tex]
[tex]y = \frac{3}{2} [/tex]
[tex]x = \frac{9 - 5x \frac{3}{2 } }{3} = \frac{ - 1}{2} [/tex]
[tex]hence \: (x = \frac{1}{2} )and \: (y = \frac{3}{2} )[/tex]
[tex]so \: x \: + y = \frac{1}{2} and \: \frac{3}{2} = 2[/tex]
