Explanation:
Given equation:
We have to find another equation which has only one solution.
Standard form of equation:


Condition for one solution.

We have to arrange other equation in the form of 
Mark all the options as a,b,c and d.




Now from the above options we can see that option
are not providing the desired result.
So
can be obtained from the last option.
As

Option D that is
is the equation from where we can obtained only one solution.
Subtract Evans scores from the mean:
X = 138 - 125 = 14
Y = 138 - 137 = 1
Subtract the mean from the score because the score is higher this time:
Z = 145 - 138 = 7
