Answer:

Step-by-step explanation:
We know i×i=i^2 which has value of -1.
We will multiply numerator and denominator by i so the denominator will no longer contain imaginary part(s).
Also multiplying by i/i does not change the value of the fraction because i/i=1.
Numerator × i gives (-5+i)i=-5i+i^2=-5i-1
=-1-5i.
Denominator × i gives (2i)i=2i^2=-2.
So the simplified version of this fraction given is:

The last simplification come from me multiplying fraction by -1/-1.
Answer:
Explanation:
In this case, you need to solve for y in y + y/a = b, if s ≠ - 1.
This is how you do it step-by-step:
<u>1. Multiply all the equation by the common denominator</u>: a

<u>2. Simplify</u>:

<u>3. Common factor:</u> y

<u>4. Divide both sides by a + 1</u>

Sorry bro its past 10pm now, hope you figured it out
