x/5 + 4 = 1
x/5 = 1 - 4
x/5 = -3
x = -3(5)
x = -15

∴the answer should be -15

Hi,

For this question, we first need to subtract 4 from both sides of the equation to get:

x / 5 = -3

Now, at this point, we need to multiply both sides of the equation by 5 in order to isolate for x alone and get:

x = -15 <==== FINAL ANSWER

+ NOTE: You might have typed in the answer choices incorrectly, since -15 is indeed the correct answer. Here's the proof:

Put x = -15 back into the original equation:

-15 / 5 + 4 = 1

-3 + 4 = 1

1 = 1 =D

Therefore, the correct answer is x = -15.

I hope that helps you out! Please let me know if you have any other questions!

Sincerely,

Andrew
