so to get rid of - 6n, you add it to both sides. getting rid of - 6n on the right, and adding it to the left

ugh, math

i hate it too

idk about #10, tho, I don't fuck with fractions

i think for #10, you convert the - 8 into 40/5 (reduce the fraction, its just 8 but in fraction form) and then youll have
-16/5 = r/3 - 40/5

hopefully that makes it easier to deal with?

I suck at math big time... mainly algebra... but I remember some of the simpler stuff

Would you times everything by 3 to isolate r?

@HUNTER4639 with what I did to #10, is that any easier to figure out?

Algebra 2 @Wardog

I think so

hmm. so with the r situation, youd times everything by the inverse I think... that part is a little foggy to me...

so youd want to do something like multiple everything with the denominator of 3 by 5, and everything with the denominator of 5 by 3 (so it all comes out to something over 15.

I forget exactly how to do that though. and fuck algebra 2. my worst math class and worst subject ever... only class I EVER came anywhere close to failing.

Ehh Geometry was harder for me loool then again this is only the 2nd week of Algebra 2...

Alrighty thanks for the help everyone <:TrumpSmile:720121948088041513>

bruh, I rocked at geometry. it seems like a lot of people are really good at algebra, OR geometry.

happy to help man

😀

...

#10 r is 72/5
-16/5 = r/3 -8
Add 8 to both sides, multiply 8 by 5 to slide it into the top of the fraction on the left
(40-16)/5=r/3
24/5=r/3
Multiply both sides by 15 to cancel out both denominators
72=5r
divide both by 5, get r
72/5=r

Do fuck am I late to the party

wait how do you go from 24/5=r/3 to 72=5r? its been a while, but I dont understand how exactly how got to that

Multiply both by 15

you would multiply 24/5 by 15/15 right?

5 cancels out left bottom, so 24*3

oh wait, 15/1

nah, 15/1

ohhhh okay. i remember now

not 15/15 because thats 1, 15/1 makes 360/5 which reduces to 72

okay

fuck I hate math lol

I'm fine with it until they add the greek letters, fuck that noise

and I guess I was wrong? multiplying both sides by 15 works the same as multiplying both sides by the inverse to get common denominators, right?

It's the same

I just said 15 cause it is the end result

okay, but doing it by 15 is quicker and has less steps

Yep

gotcha!

Mark out he denominators and cross-apply them

Or something
