Hello there!
Since we're looking for an equation to have a solution of x = -5, let's solve them from answer choice "A.)" to answer choice "D.)"
x + 10 = -5
x = -15
A.) is not correct.
Let's try B.)
-x^2 + 50 = 25
x^2 = -25
x = -5
Answer choice B.) is correct.
Let's continue looking for answer choices, just in case.
Let's look at answer choice C.)
2x = 10
x = 5
This answer is not correct.
Let's look at answer choice D.)
x < 0
This means x is less than 0, or a negative number.
This answer is not specifically correct.
Let's look at answer choice E.)
2x < 10
x < 5
This is less than 5, but does not specifically answer our chances.
Your answer is B.)
I hope this helps!
The value of x is 
Explanation:
The expression is 
Adding 
to both sides of the equation, we get,
Using log definition, if 
then 
, we have,
Using exponent rule, 
,
Simplifying, we have,
Dividing both sides by 9, we have,
Simplifying,
Thus, the value of x is
