Question

one solution of the equation 2x+y=0 is:
(A) (3,-5) (B) (3,-6) (C) (3,-7) (D) (3,-8)​

Answer 1

B) (3,-6) is the Correct Answer.

Step-by-step explanation:

Let check first one (3,-5)

therefore x = 3 and y = -5

$2 \times 3 + ( - 5 )= 1$

therefore, it is not the answer.

Let check Second one (3,-6)

therefore x = 3 and y = -6

$2 \times 3 + ( - 6) = 0$

therefore B) (3,-6) is the correct answer.
