Final answer:

To subtract the second equation from the first, you need to subtract the corresponding terms. The result is 12y = -7.

Step-by-step explanation:

To subtract the second equation from the first, we need to subtract the corresponding terms.



Starting with the x terms:

2x - 2x = 0

Next, the y terms:

7y - (-5y) = 7y + 5y = 12y

Finally, the constant terms:

-8 - (-1) = -8 + 1 = -7


Putting it all together, the result of subtracting the second equation from the first is 0 + 12y = -7, which can be simplified to 12y = -7.
