@agent0smith here is one of them if you cant help its ok :D

OpenStudy (bookworm14):

I know the concept needed here, I am just exhausted, and super stuck :(

OpenStudy (agent0smith):

Just cross multiply. Then simplify and solve the resulting quadratic.

OpenStudy (bookworm14):

idk Dani, I somehow ended up with -0.5, plugged it in and that didnt work, ive already worked tis thing like 4 diiferent ways

OpenStudy (agent0smith):

You've skipped too many steps lol. First thing is cross multiply. Then simplify

OpenStudy (bookworm14):

I did, then they turned into the similar form of ax^2 + b +c (you know once i multiplied or whatnot) i simplified that, and idek, i cant focus im too tired, but i have to get it done jus these las 2 question and im home free

OpenStudy (agent0smith):

Just show me what you got after cross multiplying

OpenStudy (bookworm14):

(n-6)(3n+1) = (3n)(n-5) 3n^2 -17m-1 = 3n^2-15n 3n^2 - 2n-1 = 3n^2 3n^2 -2n= 3n^2 +1 -2n = 1 n= -0.5

OpenStudy (agent0smith):

-6 times 1 isn't -1 silly penguin :P

OpenStudy (bookworm14):

omg im so tired, i completely didnt see that -_-

OpenStudy (bookworm14):

i worked it 3x over and still ddnt notice it, i will try again x_x

OpenStudy (bookworm14):

my new answer is -3 is that right

OpenStudy (agent0smith):

Idk, plug it in and check it works.

OpenStudy (agent0smith):

But based on your work above it looks right

OpenStudy (bookworm14):

you plug it in I am tired :'D OMG I plugged it in and it worked, I will now cry in happiness and exhaustion <3

OpenStudy (agent0smith):

Haha good :D

OpenStudy (bookworm14):

i will now apply my new found knowledge to the LAST QUESTION <3 (excuse me while my heart sings in joy and tiredness) i will let you know if my brain works right xD

OpenStudy (agent0smith):

Haha okay :D

OpenStudy (agent0smith):

What new found knowledge? That 1 times 6 equals 6? Hahaha

OpenStudy (bookworm14):

nooo, that is not what I meant Dani <3 haha im too tired to explain what i meant, you will catch on eventually xD

OpenStudy (agent0smith):

Lol sure I will :P but you already had the knowledge in this question! You just couldn't find your mistake

OpenStudy (bookworm14):
