Step-by-step explanation:
2x - 5y = -20 ⇒ 4x - 10y = -40
3x + 2y = 20 ⇒ 15x + 10y = 100
19x = 60
19 19
x = 3³/₁₉
2x - 5y = -20
2(3³/₁₉) - 5y = -20
6⁶/₁₉ - 5y = -20
- 6⁶/₁₉ - 6⁶/₁₉
-5y = -26⁶/₁₉
-5 -5
y = 5⁵/₁₉
(x, y) = (3³/₁₉, 5⁵/₁₉)
The best approximation of the solution to the system of the nearest integer values are (4, 6), or (x, y) ≈ (4, 6).

Based on the fact that you will eat only 5 pieces per day out of the bucket of 125 pieces of candy, this is an arithmetic sequence.
<h3>What is an arithmetic sequence?</h3>
An arithmetic sequence is one where the difference between the consecutive numbers in the sequence have a common difference.
In this case, the sequence will reduce by 5 and look like:
125, 120, 115, 110, 105, 100,...
The difference between each of these figures is the same and that difference is 5.
With a common difference of 5, we can say that this sequence is arithmetic.
The rest of the question:
Your bucket of Halloween candy has 125 pieces of candy in it. You decide that to ration yourself, you're going to only eat 5 pieces per day. Is this an arithmetic sequence?
