<u>Answer:</u>
x ---> 1
y ---> 5
<u>Step-by-step explanation:</u>
We are given paired values for two variables x and y and we are to determine the constant number by which each term is increased such that they are in a proportional relationship.
For x, we have the following paired values:

So here the difference between each consecutive term is 1 so the constant is 1.
And for y, we have:

In this case, the difference between each consecutive term is 5 so the constant is 5.
51 as a decimal is .51 and 100 as a decimal is 1.00
51100 as a decimal is 511

Hope that helps!!! Good luck
I will let you decide what counts as a second step,<em> </em>I'm going to write out all the steps.
starting from original equation
49n+986=-43
49n=-1029
n=-21
