Answer:
No Solution
Step-by-step explanation:
4x-2y=8
y=2x+1
Make the first equation into where it says y=.
-2y=-4x+8
y=2x-4
Substitute either equation into the other as y=.
2x+1=2x-4 or 2x-4=2x+1
Switch terms around so they're with their like terms. Make sure it becomes the opposite when switching.
2x-2x=-1-4 or 2x-2x=4+1
0=-5 0=5
Since x did not come back to equal an answer, this problem is not workable. There is no solution to it. If you were to do it a different way, there still would not be a solution to it.

Answer:
To determine the explicit rule for the arithmetic sequence of 20.5, 16, 11.5, 7, 2.5, ..., the following logical reasoning must be performed:
20.5 - 16 = 4.5
16 - 11.5 = 4.5
11.5 - 7 = 4.5
7 - 2.5 = 4.5
Thus, the explicit rule of the arithmetic sequence is that the numbers are gradually subtracted by 4.5, with which the next number of said sequence would be -2.
