Why is the range the most convenient measure of variability?
- Your data's spread from the lowest to the greatest value in the distribution is indicated by the range.
-  The calculation of this variability index is the simplest. 
- Simply subtract the lowest value from the highest value in the data set to determine the range.
How do you find the range?
- The difference between the lowest and highest values in a list or set is known as the range. 
- Put all the numbers in order before determining the range. The lowest number should then be subtracted from the highest.

Answer:
y = 1
x = -1
Step-by-step explanation:
x - 2y = -3, then x = 2y - 3
2x + y = -1
substitute for x:
2(2y - 3) + y = -1
4y - 6 + y = -1
5y = 5
y = 1
x = 2 - 3 = -1
