Which is a solution to the equation 6x + y = –4?

1 answer:

7 0

1. Make y the subject of the equation
y = -4 - 6x

2. Substitute values for guess and check
8 = -4 - (6 x 2)
8 = -4 - 12
This is incorrect.

2 = -4 - (6 x 1)
2 = -4 -6
This is incorrect.

-10 = -4 - (6 x 1)
-10 = -4 -6
This is correct.

The correct answer is C.
