Choose the correct first step(s) to solve the system using elimination.
4x + 7y = 6 and 6x + y = 2

Question

anonymous · Answer

divide both sides by X

hero · Answer

All I can say is, you have at least two other people taking the exact same class you are.

hero · Answer

Katin 95 is one of them

anonymous · Answer

Lol! I go to K12 online public school.

hero · Answer

I know

anonymous · Answer

Ok? Lol. Can you help me put what Durviel just said into an equation??

hero · Answer

I wouldn't use durviel's method

hero · Answer

I have my own methods

anonymous · Answer

Oh, well can you use your method and put it in an equation for me? :)

anonymous · Answer

everyone has different methods. some work better for others. correct?

hero · Answer

durviel, I'm curious to see your method

hero · Answer

By the way, it says use elimination

anonymous · Answer

i would find x first. then, when i have that answer, i use it to find y. i was taught that way. but maybe your way does work better.

anonymous · Answer

I just want an answer lol.

hero · Answer

Originally, you said "divide both sides by x". I was waiting to see how you would use that to solve it.

anonymous · Answer

how would you do it? i am hear to learn so... yeah

hero · Answer

You first

anonymous · Answer

He just told you his method, Lol.

anonymous · Answer

one sec....

hero · Answer

I want to see the method where you divide both sides by x only.

anonymous · Answer

the way i was taught is you find x first. then when you plug in x, you could find y.

anonymous · Answer

What was that drivel between Durviel and Hero lol...Thought you were supposed to be helping...

I will help. 

So we have: 4x + 7y = 6 and 6x + y = 2

The correct first step is to multiply the second equation by 7 to get:
42x + 7y = 14

We can then eliminate the 7 by subtracting equation 1 (unchanged) from equation 2.
