Three equally spaced points ( . . . ) often used to represent an omission of words in a quotation are best known as ellipsis. They are also known as ellipsis dots, suspension points, or simply ellipsis.
<h3>Usage</h3>
"For example, I may be writing an article to be published in a journal and not include ellipsis. . ."
In summary, we utilise ellipsis to indicate that a list goes on beyond those items actually spelled out in the text.

Oh wow that long I’ll get back to you if I have an answer when I finish reading
Answer:
-12
Explanation:
We are given information to solve for 2 variables x and y. To solve this I substituted 3x for y in the equation 5x - 4y = 21
So substituting gets us 5x - 4(3x) = 21
and we can solve the equation for x
5x - 12x = 21
-7x = 21
x = -3
Now that we have found x, we can find y simply by putting it in the equation y = 3x
y = 3(-3) = -9
Once we have both variables, we can find the answer to x + y
-3 + -9 = -3 - 9 = -12
So the answer to the question
x + y = -12
