Repost, hopefully we can complete this dang equation. >:I

FriskIsNice:

Macho14:

okay, first of all, we set the equations equal to each other: \[-9x+3=4x-10\]

FriskIsNice:

We got this! I’ll try to fix my brain up to think too πŸ˜…

Macho14:

remembering that we need to isolate x, what do we do first?

FriskIsNice:

Subtract 3 on both sides?

FriskIsNice:

Macho14:

yes, that gives us: \[-9x=4x-10-3\] simplifies to \[-9x=4x-13\]

Macho14:

so, what next?

FriskIsNice:

Hnnnnn I forgot- my mom is watching something super loud in my room and I keep getting distracted yet she expects me not to get distractedddd-

FriskIsNice:

Macho14:

-4x on both sides

Macho14:

remember that we need to isolate x

Macho14:

\[-9x-4x=-13\] simplifies to \[-13x=-13\]

Macho14:

so, what do you think we do now?

Macho14:

we still have to get x alone

FriskIsNice:

Uhhhh do -13 divided by -13?? But thst would get 1

Macho14:

yes, that is correct!

Macho14:

\[x=1\] because a negative divided by a negative = a positive

FriskIsNice:

πŸ˜„πŸ˜„

Macho14:

\[-13x/-13=-13/-13\] =\[x=1\]

Macho14:

now you have to plug your answer into anyone of the equations to solve the y value

Macho14:

so far we have: (1, ?)

FriskIsNice:

And for 4x - 10, I’d just have to put 1 in the place of x?

Macho14:

yes: \[4(1)-10= ?\] \[4-10=\]\[-6=y\]

Macho14:

the answer: \[(1,-6)\]

FriskIsNice:

Yes! It’s right! But I gtg rn- OH MY JESUS CHRIST- THIS ONE LOOKS WORSE!

Macho14:

you are all done, so remember when using this method: Set both equations equal to each other. Solve for x. Pick one of the equations. (doesn't matter which) To solve for y.

Macho14:

that's ok, I can help

FriskIsNice:

Well I gotta go rn ;-;”

Macho14:

I see, I hope you do well

Macho14:

and I hope I provided good help

FriskIsNice:

I’ll close this one.. and post a new one with this equation tomorrow, see you tomorrow, hopefully, friend! And DOTN worry, you did 😊

KingGeoGoat:

macho you are really smart

Macho14:

thx I guess, but I accidentally told you something wrong on one of your questions.
