Answer:
x = 7 & y = 8
Step-by-step explanation:
We know that
Mean = Sum of terms/Total terms
=> Mean = 4 + 6 + x + y + 10/5
=> Mean = 20 + x + y/5
Now,
Median = (n + 1)/2
=> Median = (5 + 1)/2
=> Median = 6/3
=> Median = 3rd term = x
So,
x = 20 + x + y/5
x × 5 = 20 + x + y
5x = 20 + x + y
5x - x = 20 + y
4x = 20 + y
Since x and y are in order so,
Possible outcomes will be 7,8 & 9
(7,8) & (8,9) & (7,9)
Taking x = 7 and y = 8
4(7) = 20 + 8
28 = 28
Hence,
x = 7 and y = 8

The value of c that makes the equation true is: c = -13/21.
<h3>What is an Equation?</h3>
An equation is a mathematical statement whose values on the right and left sides are equal.
Given:
c + 15 = 23c + 2 − 43c
Find the value of c
c + 15 = -20c + 2
c + 20c = -15 + 2
21c = -13
c = -13/21
Thus, the value of c that makes the equation true is: c = -13/21.
