Nahil and Mae work at the same company. Nahil has been at the company 5 times as long as Mae. Nahil's time at the company is 8 more than 3 times Mae's time. The following system of equations models the scenario:

[tex]\ \textless \ br/\ \textgreater \ \begin{array}{l}\ \textless \ br/\ \textgreater \ x = 5y \\\ \textless \ br/\ \textgreater \ x = 8 + 3y\ \textless \ br/\ \textgreater \ \end{array}\ \textless \ br/\ \textgreater \ [/tex]

How many years has each person been employed by the company?

A. Nahil has been with the company for 15 years, while Mae has been there for 3 years.
B. Nahil has been with the company for 20 years, while Mae has been there for 4 years.
C. Nahil has been with the company for 25 years, while Mae has been there for 5 years.
D. Nahil has been with the company for 30 years, while Mae has been there for 6 years.


Sagot :

Given the scenario where Nahil and Mae work at the same company, we have two pieces of information:

1. Nahil has been at the company 5 times as long as Mae.
2. Nahil's time at the company is 8 more than 3 times Mae's time.

These statements can be converted into the following system of equations:
[tex]\[ \begin{aligned} x &= 5y \\ x &= 8 + 3y \end{aligned} \][/tex]

Here, [tex]\(x\)[/tex] represents Nahil's time at the company, and [tex]\(y\)[/tex] represents Mae's time at the company.

### Step-by-Step Solution:

1. Set the equations equal to each other:

Since both equations equal [tex]\(x\)[/tex], we can set the right-hand sides equal to each other:
[tex]\[ 5y = 8 + 3y \][/tex]

2. Solve for [tex]\(y\)[/tex]:

To isolate [tex]\(y\)[/tex], subtract [tex]\(3y\)[/tex] from both sides of the equation:
[tex]\[ 5y - 3y = 8 \][/tex]
Simplifying this, we get:
[tex]\[ 2y = 8 \][/tex]

Next, divide both sides by 2:
[tex]\[ y = \frac{8}{2} = 4 \][/tex]

So, Mae has been at the company for 4 years.

3. Find Nahil's time ( [tex]\(x\)[/tex] ):

Now that we know [tex]\(y = 4\)[/tex], we can substitute this value into either of the original equations to find [tex]\(x\)[/tex]. Using the first equation:
[tex]\[ x = 5y \][/tex]

Substitute [tex]\(y = 4\)[/tex]:
[tex]\[ x = 5 \cdot 4 = 20 \][/tex]

So, Nahil has been at the company for 20 years.

### Conclusion:

Nahil has been with the company for 20 years, while Mae has been there for 4 years. Therefore, the correct answer is:

Nahil has been with the company for 20 years, while Mae has been there for 4 years.
