do you mean like solve for x and y?

1. Multiply the second equation by 2
2. Add both equations together.

But how do you figure out what to multiply it by?

find a number that cancels out the other

leaving just one variable

But how?

Do the same thought process for the second problem you are working on.

Could you still take me through the steps on the one i just posted? Sorry...

Nvm

Hey i actually did tht one correctly..

Say whattt

multiply then add them together

So y is -3 and x is 11?

LCD only applies to fractions.

Whats lcd?

Least Common Denominator

This is confusing.

It's so obvious, it's confusing for you @mintymint

:(

Thank you.

Try it out, if your still confused I could try and help

@mintymint, please check your messages.

wouldn't you multiply the second equation by a - 7 instead of 7 ?

@texaschic101, my steps speak for itself.

Why would you multiply with negatives, when you can have a higher chance of making mistakes?

but your steps won't cancel out the x

YOu could subtract the two equations?

Read the steps again @texaschic101

oh, I didnt subtract, I added......can it be done either way ?

It's the same process.

I dont understand how you got 36y in your first solution

oh wait, I think I know......-21y - (-15y) never mind I see

oh wait....15y - (-21y)...sorry I understand now

Well, that's good.

sorry about the trouble.....you are a patient person

smart too

You cannot avoid math. Math is used to create everything.

P.s. thanks for the storybut im not 5 lol

Well yes, or you can just tell a story.

But it cant solve everything.

Math is about the closest thing there is to solving everything.

Math is solely responsible for the advancement of humanity.

Without math, we're still living in the stone ages.

I wonder how math begun. Isnt it amazing how ipads are built from technically natuaral resources?

If you had two worlds: One knew math, the other knew writing....which one would advance the fastest?

Well in order to figure out.math you must communicate

Math IS a form of communication.

...and sentences.

But bycommunicating in words is how onecomes to understand a concept of math

By disease i mean cancer. I mean my mom a few years back had cancer so i.get it.

There is a cure for disease, and believe it or not, it is mathematical in nature.

What about cancer, what makes it so different

Or, maybe all parts of our body are branches of living things. We are just the main control.

wow.......this is deep !!!

Very tightly

Ps how old are you you could be a doctor

I don't go around openly professing my age.

doctor or biologist ...told you hero was smart

As far as I'm concerned, I'm ageless

And i assume youre an adultof some sort maybe? Well im 14.

Were part of the matrix. Ha, no.

We can also sleep and turn on like compiters and need to "recharge" like computers.

Yes @mintymint, now you're getting it

If there is several how come we dont have the knowledge to figure it out?

Yes but the people trying to figure it out is doctors

Whom of which should be knowlegable

I have to go but will read thisand ya but then how come doctors cant?

In order to know the body, you must understand it from a more holistic point of view.
