Answer:

(5,3)

Step-by-step explanation:

The given equations are;

[tex]3x-2y=9...(1)[/tex]

[tex]x+y=8...(2)[/tex]

Multiply equation (2) by 2

[tex]2x+2y=16...(3)[/tex]

Add equation (3) and equation (1)

[tex]3x+2x=9+16[/tex]

5x=25

x=5

Put x=5 into equation (2)

5+y=8

y=8-5=3

Hence the solution is

(5,3)
