1/a-b=6, then a=

OpenStudy (aripotta):

ok, to get a by itself we gotta add b on both sides

OpenStudy (anonymous):

yeah...

OpenStudy (aripotta):

or wait.

OpenStudy (anonymous):

1/a-b

OpenStudy (anonymous):

I got 1/a=-6b

OpenStudy (anonymous):

is that right?

OpenStudy (anonymous):

a/1=1/-6b?

OpenStudy (anonymous):

nope

OpenStudy (aripotta):

you can multiply both sides by a - b

OpenStudy (anonymous):

ahh

OpenStudy (anonymous):

look

OpenStudy (anonymous):

a-b/1=1/6

OpenStudy (anonymous):

a-b=1/6

OpenStudy (anonymous):

a=1/6+b

OpenStudy (anonymous):

that's the answer

OpenStudy (aripotta):

but it's 1/a - b not a - b/1?

OpenStudy (anonymous):

yeah...

OpenStudy (anonymous):

you can do reciprocals

OpenStudy (anonymous):

1/a-b=6

OpenStudy (anonymous):

a-b/1=1/6

OpenStudy (anonymous):

see what I did?

OpenStudy (aripotta):

no...i got a = 1 + b

OpenStudy (anonymous):

I took the reciprocals of the numbers and made them equally equivalent

OpenStudy (anonymous):

how?

OpenStudy (anonymous):

the answer booklet says b+1/6

OpenStudy (anonymous):

look it

OpenStudy (anonymous):

1/a-b=6

OpenStudy (anonymous):

a-b/1=1/6

OpenStudy (anonymous):

a-b=1/6

OpenStudy (anonymous):

a=1/6+b

OpenStudy (anonymous):

see what I did?
