Answer:
14x + 7y = 21 is your answer.
Step-by-step explanation:
Standard form is Ax + By = C
Isolate the constant. Note the equal sign, what you do to one side, you do to the other. Add 7y to both sides.
14x = -7y + 21
14x (+7y) = -7y (+7y) + 21
14x + 7y = 21
14x + 7y = 21 is your answer.

Answer:
Here is the complete question attached with.
The mean score would decrease more than the median score.
Step-by-step explanation:
The numbers for which we have to find the mean and median are:

Here the mean, 
Median,
as median is the middle term if the observations are arranged in ascending order.
Now as the question says that we have to add a zero to see its effect.
So adding a zero we have
Mean 
Median
,as number of observations is even terms so we will add two middle numbers and divide it with
.
So we can conclude that the mean is having more variation than the median.
Mean shows as variation of
where as Median shows a variation of
only.
So our final answer is option D that is "The mean score would decrease more than the median score."
