✔ 最佳答案
x/5 = - 3
x = - 15
None of above!!!!
x/5 + 4 = 1
x/5 = 1 - 4
x/5 = -3
x = -3(5)
x = -15
â´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
