Question

Which equation results from adding the equations in this system? x + 6 y = 9. Negative x + 2 y = negative 15. 8 y = negative 6 8 y = 6 4 y = 24 4 y = negative 6Which equation results from adding the equations in this system? x + 6 y = 9. Negative x + 2 y = negative 15. 8 y = negative 6 8 y = 6 4 y = 24 4 y = negative 6

Answer 1

8y = -6

Explanation:

I got it right on Edge 2020

Also: Plug in the slope 8 and the y-intercept -6 to check the answer. It is correct.

Answer 2

8y = - 6

Explanation:

Given the 2 equations

x + 6y = 9 → (1)

- x + 2y = - 15 → (2)

Adding the 2 equations term by term gives

(x - x) + (6y + 2y) = (9 - 15), that is

8y = - 6
