First u add ten to both sides to cancel out. Now you have 14=-7s. Since you are trying to do the opposite operation, you divide by -7 on each Sides. Now you have -2=s. Hope this helped
Answer:
Option B. 0.71
Step-by-step explanation:
There are 200 males and 300 female employees in the company.
The percentage of its employees are given who stayed for at least 1, 2 and 3 years.
1 year 2 years 3 years
Male 0.67 0.45 0.20
Female 0.73 0.64 0.39
Number of male employees who stayed at least one year = 0.67 × 200
= 134
Number of female employees who stayed at least 1 year = 0.73 × 300
= 219
Total employees who stayed at least 1 year = 134 + 219 = 353
Total employees in the company = 200 (males) + 300 (females)
= 500 employees
Probability that an employee stayed for at least one year = 
= 0.706 ≈ 0.71
Option B 0.71 is the answer.

The answer to your question is A
To solve equations like this we need to do inverse operations.
First we need to build an equation: 9+3x=21
We pass the nine to the other side, subtracting the 9 to 21, that leaves us with 3x=12
After that we just divide 12 by 3, wich gives us x=4, or, as it says in the question: n=4
Now let's double check:
N=4, since 3*4=12 and 12+9=21
Hope it is helpful :)
