Answer 2

Answer:

if X=9 ,y=4

Step-by-step explanation:

in the first equation

2x+y=17

so we have to put the value of X and y

therefore,. (2×9)+4=17

= 18+4 =17

=. 22 ≠17

in the second equation

X+y=17

9+4=17

9≠17

in the third equation

x+2y =17

9+(2×4)=17

9+8 =17

17=17

I hope you understand the answer
