Hey there!!
Given:
... A=3B+7C
Subtracting 7C on both sides:
... A-7C=3B
Dividing by B on both sides:
... (A-7C)/3=B
<em>Hope my answer helps!</em>
I believe it is neither
For one if you plug in either of them the first one is going to be negative 3. But if you use the second one then your answer would be -3+12= -10 but -3+12 is 9 so I would go with neither because I don't see how it's both
Answer:
25
Step-by-step explanation:
Let n be the first integer.
Then the second integer will be (n + 1).
And the third will be (n + 2).
The sum is 78. Therefore:

Solve for n. Combine like terms:

So:

Therefore:

Therefore, the first integer is 25.
So our sequene is 25, 26, and 27.
The integer closest to zero will thus be 25.
