I didn't see all this

@Warren H One thing you might notice at the beginning: think about the equation -4w = 6/7

one things you might notice is that the left side is -4 * w, and the left side is a positive number (specifically 6/7)

that means w times a negative number is something positive

so whatever w is, w must be some negative number, since -4 times a positive number would be negative.

@Warren H This ^ might help as a kind of double check on your work, thinking what sign the final answer should have

Okay yeah that makes sense.

Ive been working a lot with linear equations

@Warren H Yeah they are an important building block for a lot of things but there can be a lot to keep track of when getting used to them. Any thoughts in particular about linear equations? Let us know if you have any questions in the future!

Haha I don't like them lol. The worst part of math for me is fractions, and finding missing numbers like x lol

@Warren H haha yeah if you remember up there ^^^ the first way I wanted to solve for u... first thing I did was cross-multiplied the denominators because I don't like using fractions either if I don't have to.

Are you doing this for a math major?

Yeah I will try to remember that

And nope not at all. I'm majoring in media production. This is just a required core class. Even tho I took 4 years of math in high school ðŸ™ƒ

@Warren H yep it's a common core req for almost everybody. welp, feel free to ping <@&387091385075105804> for help here throughout the semester!

What's AE?

@Warren H Academic Expert, it pings everyone has volunteered to make themselves available to anyone asking questions. Lots of fellow students and teachers and former teachers here

Although pinging @here works pretty well too

Ah okay. That's good to know @ThisIsChris

If you're still here I need some clarification on a problem that I think I did correctly but it's not approving

-2z - 4z = 19+ 4

left side is -6z

right side is 23

so -6z = 23

divide both sides by -6

so z = 23/(-6) or equivalently z = -23/6

Oh

lol I didn't do the signs right. I got 23/6 that's why

that'll do it

ðŸ˜† it's really hard to pay attention to that sometimes. Especially on timed exams

Yeah, best thing I could advise is that whenever you see a negative sign ANYWHERE, double check at the end that the signs look right

if all the numbers are positive then you probably don't have to be too careful. It's just when a negative sign appears, keep going, but walk through it again at the end

Yeah that's a good way to check. I try my best lol

Anyone @here to help with another math question?

I might could. I haven't done math in a bit, but I can do things like the last question posted.

I know the answer to this question, I'm just not sure how to solve to get to it

6/9 * 3/12 squared - 4/6

Is there an equals sign?

No. supposed to solve it

PEMDAS

I meant I knew the answer

Order of operations

Yep did that

Would a photo help for reference?
