Given the expression (8+3i)+(-2+i)
We need to simplify it.
(8+3i)+(-2+i)
First we have to remove the parenthesis.
8+3i-2+i
As we know that multiplication of positive and negative is negative.
Now we will add or subtract like terms. Like terms means here i with i and constant term with constant term. So here we will add 3i and i. Also subtract 2 from 8.
8-2 +3i+i
6+4i
We have got the required answer.
The simplified answer is 6+4i.
The value of g in terms of other variables is 
Given the expression;
gh-f=g-h
We are to express g in terms of other variables as shown;
gh-f=g-h
Collect the like terms
gh - g = f + h
Factor out g
g(h - 1) = f + h
Divide both sides by h-1

Hence the value of g in terms of other variables is

= 8 21/40
= 8 + 21/40
= 8/1 + 21/40
= (8/1 * 40/40) + 21/40
= 320/40 + 21/40
= 341/40
= 341 ÷ 40
= 8.525
