Answer:
s = 5/4
Step-by-step explanation:
Solve for s:
86 = 8 s + 76
86 = 8 s + 76 is equivalent to 8 s + 76 = 86:
8 s + 76 = 86
Subtract 76 from both sides:
8 s + (76 - 76) = 86 - 76
76 - 76 = 0:
8 s = 86 - 76
86 - 76 = 10:
8 s = 10
Divide both sides of 8 s = 10 by 8:
(8 s)/8 = 10/8
8/8 = 1:
s = 10/8
The gcd of 10 and 8 is 2, so 10/8 = (2×5)/(2×4) = 2/2×5/4 = 5/4:
Answer: s = 5/4

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!
