Can someone explain to me how I can eliminate one of the variables to solve this equation for one of the variables?

Answers

Answer:

In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.

Answer:

x = 1 and y = 4

Step-by-step explanation:

Multiply the top equation by 7 on both sides, and then cancel it out:

7(5x + y) = 7(9)

35x + 7y = 63

Now use this equation to cancel out -7y on the second equation:

35x + 7y = 63

10x - 7y = -18

45x = 45

x = 1

Now that we have our x-value, we can plug it into one of our two original equations:

5(1) + y = 9

y = 4

Read the excerpt from an interview with Florence Griffith-Joyner.


WILL: I know that you dropped out of college in 1979 to help support your family. It seems like family must be very important to you.


FLORENCE GRIFFITH-JOYNER: Yes. Family is first in my life. It was a very difficult decision for me to drop out of college at that time. Growing up in poverty, I didn't have the financial support that I would have needed to go to college. I wasn't offered an athletic scholarship. I wasn't offered an academic scholarship. I thought, "How am I going to stay in school?" So I enrolled in school, and I thought, "I really want to run, but I know I have to concentrate on my academics as well." I tried a year of college, and I thought, "I can't continue because I have no financial support." I had to take the bus two hours to school, two hours back. The need was greater than what I could afford.


What is the purpose of the interviewer’s question?

A. to share Florence Griffith-Joyner's training techniques
B. to share Florence Griffith-Joyner's family recipes
C. to share Florence Griffith-Joyner's commitment to family

There will be an estimated amount of 1125 faulty souvenir tokens.

Step-by-step explanation:

Hi!

So, let's do this problem out.

So we for every 400 tokens, 3 are faulty

Let's write that in a ratio

3:400

Ok, great!

So, now we know that:

3:400 = x:150,000

We can set up a percent proportion

[tex]\frac{3}{400} =\frac{x}{150,000}[/tex]

To find x, we do:

[tex]x=\frac{3*150,000}{400}[/tex]

[tex]x=\frac{450,000}{400}[/tex]

[tex]x=\frac{4,500}{4}[/tex]

[tex]x=1125[/tex]

There will be an estimated amount of 1125 faulty souvenir tokens.

Let me know if you have any questions.
