Step-by-step explanation:
You can add any multiple of one equation to the other without changing the solution to the system.
In the first answer choice the first equation is added to the second, and the first equation is left alone.
In the third answer choice, the first equation is subtracted from the second, and the second equation is left alone.
___
The other answer choices have strange combinations of sums and differences that result in systems of equations with different answers.

<u>Arithmetic Sequences </u>
The arithmetic sequences are those where any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.
The equation to calculate the nth term of an arithmetic sequence is:
Where
an = nth term
a1 = first term
r = common difference
n = number of the term
We are given the arithmetic sequence:
10, 12, 14, 16, ...
Where a1=10 and
r = 12 - 10 = 2
Thus the general term is:
