Question

brainfreeze: how do i remove m from this equation?

Answer 1

\[\frac{ r_1 }{ m_2 } - \frac{ r_2 }{ m2 } = 1\]

Answer 2

the equation "looks like this"

Answer 3

i need only r1-r2 on that side, but my brain is malfunctioning

Answer 4

anyone?

Answer 5

do you mean "how do I remove \(m_2\)" from the equation?

(rather than m)

Answer 6

both m's

Answer 7

i don't know why this is confusing me..

Answer 8

both m's are \(m_2\) - correct?

Answer 9

m1 and m2 are different

Answer 10

which is why i numbered them

Answer 11

you have numbered them both as \(m_2\)

Answer 12

then i made a mistake

Answer 13

\[\frac{ r_1 }{ m_2 } - \frac{ r_2 }{ m_1 } = 1\]

Answer 14

in which case \(m_1\) and \(m_2\) are two different variables. so what do you mean when you say you want to remove m?

Answer 15

i want them on the other side

Answer 16

so you want to isolate \(m_1\) and \(m_2\) on one side of the equation?

Answer 17

i want to have this : \[r_1-r_2 = m_2 ...\]

Answer 18

exactly

Answer 19

I don't believe you can as you will get this:\[\frac{ r_1 }{ m_2 } - \frac{ r_2 }{ m_1 } = 1\]therefore:\[\frac{r_1m_1-r_2m_2}{m_2m_1}=1\]therefore:\[r_1m_1-r_2m_2=m_2m_1\]

Answer 20

the best you could then do is divide both sides by, say, \(m_1\) to get:

Answer 21

so..i'm not just going full-retard

Answer 22

\[r_1-r_2\frac{m_2}{m_1}=m_2\]

Answer 23

hehe - no - you are definitely not stupid my friend! :)

Answer 24

phew, what a relief.
But now i have to start all over again with my equation

Answer 25

thanks though!
