Question

solve z+4/z=-5

Answer 1

\[\frac{z + 4}{z} = -5\]\[-5z = z + 4\]\[-5z - z = 4\]Can you solve for z now?

Answer 2

Z equals -5. You can substitute -5 into the equation z+4 because both z's are the same.

z+4=?
-5+4=?
-5+4=-1

Check Your Answer:

Since we now have what 4 and z equal together, we can take out a number to see if we did this right. I will take out z so that we can solve for it.
z+4=-1
z=-1- 4 (Subtract 4 to the other side to isolate the variable)
z=-5
Since we already know that z equals -5 and in this equation we got -5, our answer is correct!

So, our answer to your question is -1. Hope this helps :)!

Answer 3

@MysticBell The problem has a z in the denominator meaning that -1 is not the answer.

Answer 4

Nor is it -5

Answer 5

@Calcmathlete Oh, I am sorry. It looked like they we giving the value of the variable to me. I'll read more carefully in the future. Again, I am sorry.

Answer 6

Alright. It's fine. Also. Please don't give the answer. Even with a really good explanation, there is just too much a chance that the asker is someone who just wants the answer. As soon as they find the answer, they won't take another look at the problem. So please guide them to the answer :)
