Good job! Your answer is correct, and you would just put the final answer as [tex]\sf{(2,5)}[/tex].

Good job again :)
The answer is correct and you can always check your answer by substituting you the values in the question,

y + 2x = 9


according to your answer


5+ 2(2) = 9

9 = 9  (the answer is correct)
