-14= 2/3t? t=?

OpenStudy (anonymous):

Okay

OpenStudy (anonymous):

we want to start by getting that variable out from under that fraction

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

did you put the ? to represent a quaestion or a symbol?

OpenStudy (anonymous):

in the top one

OpenStudy (anonymous):

I put a question mark to resemble what the answer is, and forget I put the other question mark there

OpenStudy (anonymous):

just making sure

OpenStudy (anonymous):

okay so in order to get the variable and its number thats adjoined to it out we need to do the opposite of whats currently happening to both sides

OpenStudy (anonymous):

right now we have a division, so whats the opposite of a division?

OpenStudy (anonymous):

t2/3=-14?

OpenStudy (anonymous):

oh

OpenStudy (anonymous):

multiply

OpenStudy (anonymous):

Yes

OpenStudy (anonymous):

if we multiply both sides by 3t the fraction becomes 3t*2/3t which is 1* 2 /1 -> 2/1 and everything always has an invisible /1 under it so we can act like it dissapears

OpenStudy (anonymous):

rhonda was that necessary??

rebeccaxhawaii (rebeccaxhawaii):

\[\frac{ 14 }{ 1 }*\frac{ 3 }{ 2 } = t\]

RhondaSommer (rhondasommer):

sorry -14

OpenStudy (anonymous):

i'm confused a bit
