The values of x and y are 8 and 10, respectively
<h3>How to determine the values of x and y?</h3>
The list of the numbers is given as:
4, 7, x, y, 11
The mean and median of the five numbers are the same.
The median is the middle number.
So, we have
Median = x
This means that
Mean = Median = x
The mean is calculated as:
Mean = Sum/Count
This gives
(4+ 7+ x+ y+ 11)/5 = x
Evaluate the sum
(22 + x + y)/5 = x
This gives
22 + x + y = 5x
Evaluate the like terms
4x = 22 + y
Based on the order of the list, we have:
7 < x < y < 11
Assume y = 10
4x = 22 + 10
This gives
x = 32/4
x = 8
Recall that:
7 < x < y < 11
This means that
7 < 8 < 10 < 11
The above is true
Hence, the values of x and y are 8 and 10, respectively

Answer:
x = 2 and y = 1
Step-by-step explanation:
A) 5x+y=11
B) x - y = 1.
(Solving by substitution)
B) x - 1 = y
A) 5x + (x -1) = 11. 6x-1=11. 6x = 11+1
6x = 12
x = 12/2. x = 2
B. 2 - 1 = y. y = 1
I️ think x=4 if that’s what your looking for?
