Answer:

1. y = -2x - 4

2. y = -7/2x - 17/2

Step-by-step explanation:

14x + 7y = -28

-14x            -14x

7y = -14x -28

--       --      --

7       7       7

y = -2x - 4

-----------------------------------------------------

-7x - 2y = 17

+7x         +7x

-2y = 7x + 17

--       --     --

-2      -2    -2

y = -7/2x  - 17/2
