Answer:
y=-50x-20
Step-by-step explanation:
<span><u>Answer </u>
Common difference = -4.5
<u>Explanation. </u>
An arithmetic sequence is a sequence in which the next term is found by adding a constant to the current term. This constant is called the common difference.
If a, b, c, d, e, ….is an arithmetic sequence, then the common difference will be,
Common difference = b-a=c-b=d-c=e-d…..
Now the question above common difference is;
Common difference = (-22.5)-(-14)=-4.5

I think the answer is Neither x nor y will eliminate because, by looking at the two equations we can add them and y will be elminated and we will have x-value but we can substitute the x value into one of the equation and obtain y value again.Hope this will help.Sorry If I was wrong .
The sum of (2x-5y) and (x+y)
(2x-5y)+(x+y) combine like terms
3x-4y
