If nx + 7 = 8 while kx - 7 = 10, what is the value of n/k?

Question

asnaseer · Answer

get an expression for nx from the first equation
then get an expression for kx from the second equation
then divide one by the other

asnaseer · Answer

does that make sense?

yeah i got the answer 1/17

asnaseer · Answer

perfect! :)

do we assume x != 0?

asnaseer · Answer

I would think so.

zzr0ck3r · Answer

maybe make a note saynig x != 0

asnaseer · Answer

depends on what "level" of maths you are studying at @lawls

zzr0ck3r · Answer

o wait it cant be because nx would not equal 1

asnaseer · Answer

true - x=0 would not satisfy either equation - so it not a viable answer.

word

asnaseer · Answer

hope we haven't confused you @lawls :)

zzr0ck3r · Answer

yeah just dont read my first remark or beyond:)

zzr0ck3r · Answer

unless you want to kiss your teachers but:)

it's ok guys. it's only a sat level question.

asnaseer · Answer

ok - thats good, you can ignore the discussions about x=0 then. :)

asnaseer · Answer

unless you're actually interested in knowing why it was brought up by @zzr0ck3r ?

anonymous · Answer
