-4w = 6/7
So divide both sides by -4 and I get 6/7 * 1/4? Or -1/4
Yep:
divide both sides by -4, so w = 6/(7* -4)
6 is 2\*3 and -4 is 2\*-2
so w = (2\*3) / (7\*2\*-2)
then cross out the two on top and bottom
so w = 3/(7*-2)
so w = 3/(-14) or equivalently w = -3/14
@Warren H the second one
the negative sign stays with the number it is attached to
Okay. So I got 3/7 the first time. But it's actually negative 3/14ths? Or -3 over 14?
Yep. If you're asking if there is a difference between " negative 3/14ths vs -3 over 14" the answer is no, they have the same value
Uh. Divide both sides by 9
Oh geez
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?
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 🙃
@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
@Warren H sure!
-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
😆 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.
