The answer is -3.
To find this, we simply have to solve the equation and leave only the blank and the parenthesis that it is with on the right side. Then we can divide by the parenthesis. The work for this is done for you below.
____(x - 3) + 2x = -(x - 5) + 4 ----> Distribute the -1 to the parenthesis.
____(x + 3) + 2x = -x + 5 + 4 ----> Simplify
____(x + 3) + 2x = -x + 9 ----> Subtract 2x from both sides
____(x + 3) = -3x + 9 ------> Divide both sides by x + 3
____ = -3.

Answer:
12
Step-by-step explanation:
Given :
Male Female Total
Registered 60
Non registered 40
Total 20 80
Solution :
N= 100
Formula of expected frequency = 
= expected frequency for the ith row/jth columm.
= total in the ith row
= total in the jth column
N = table grand total.
So, using formula 
![E_{22]=\frac{80 \times 40}{100}](https://tex.z-dn.net/?f=E_%7B22%5D%3D%5Cfrac%7B80%20%5Ctimes%2040%7D%7B100%7D)
Expected frequency table
Male Female Total
Registered 12 48 60
Non registered 8 32 40
Total 20 80
So, the expected frequency for males who are registered voters are
