The required solution of the equation is (2,5). The correct option is A. (2,5).
[tex]y=x+3.....(1)\\2x+y=9......(2)[/tex]
putting the value of y from eq. 1 in eq. 2 we get,
[tex]2x+x+3=9\\3x=9-3\\3x=6\\x=2[/tex]
putting the value of x=2 in eq. 1 we get,
[tex]y=2+3\\y=5[/tex]
Hence, the required solution of the equation is (2,5).
