X + y = 2
Substitute x + 8 into y
x + x + 8 = 2
2x + 8 =2
(Subtract 8 from both sides)
2x = -6
(Divide both sides by 2)
x = -3

Subsitute x = -3 into either equation to find y
x + y = 2
-3 + y = 2
(Add 3 to both sides)
y = 2 + 3
y = 5

Or y can be solved for using:
y = x + 8
y = -3 + 8
y = 5

A data set of with whole numbers has a low of 20 and a high value of 89

Vikentia [17]

Answer:

The range is 69

Step-by-step explanation:

We have that the least value of the data set is 20 and the highest value is 89.

From the available information, we can only find the range of the data set.

The range is the highest value minus the least value.

This implies that, the range is $89-20=69$
