If x = 2 then solution of 2x + 3y = 13 is A) (2, 9) B) (2, 3) C) (3

1.	If x = 2 then solution of 2x + 3y = 13 is A) (2, 9) B) (2, 3) C) (3, 2) D) (9, 2)
Answer» Correct option is (B) (2, 3) Put x = 2 then 2x + 3y = 13 \(\Rightarrow\) 3y = 13 - 2x = 13 - 2 \(\times\) 2 = 13 - 4 = 9 \(\Rightarrow\) y = \(\frac93\) = 3 \(\therefore\) (2, 3) is a solution of 2x+3y = 13. Correct option is B) (2, 3)

If x = 2 then solution of 2x + 3y = 13 is A) (2, 9) B) (2, 3) C) (3, 2) D) (9, 2)

Answer»

Correct option is (B) (2, 3)

Put x = 2 then 2x + 3y = 13

\(\Rightarrow\) 3y = 13 - 2x = 13 - 2 \(\times\) 2 = 13 - 4 = 9

\(\Rightarrow\) y = \(\frac93\) = 3

\(\therefore\) (2, 3) is a solution of 2x+3y = 13.

Correct option is B) (2, 3)
