Question

Solve the system y = 3x + 2 and 3y = 9x + 6 by using graph paper or graphing technology. What is the solution to the system?

Answer 1

a.No Solutions

b.Infinite Solutions

c.(3, 2)

d. (9, 2)

Answer 2

Well if you look at both equations, they are exactly the same.
y = 3x + 2
3y = 9x + 6

The last equation can be factored and turns out to be
y = 3x + 2
As you can see they are the same so what do you think the answer is?

Answer 3

I get how to do it and all but I'm confused whether it's infinite solutions or no solutions or maybe all the choices given.

Answer 4

Well there are many reasons for why it is one of those answers. I'm going to let you try to get this on your own. My first advice is plug any number in for x in both equations. Tell me if you see a pattern.

Answer 5

The equations are the same and the answers are as well. So then ...:)

Answer 6

It has infinite solutions?

Answer 7

Yes because every answer you plug equal out to be the same for both equations. So it is infinite solutions.

Answer 8

I'm glad you didn't give me the answer but explained it!! Thanks, Thanks:)

Answer 9

No problem. People come on here to just look for answers. Isn't it better to understand the concept because you can't come on here during tests. So i try to help as much as i can. I am a student myself so I understand what it is like.

Answer 10

Exactly!! Thank you once again:)
