Question

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

Answer 1

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

Answer 2

does that make sense?

Answer 3

yeah i got the answer 1/17

Answer 4

perfect! :)

Answer 5

do we assume x != 0?

Answer 6

I would think so.

Answer 7

maybe make a note saynig x != 0

Answer 8

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

Answer 9

o wait it cant be because nx would not equal 1

Answer 10

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

Answer 11

word

Answer 12

hope we haven't confused you @lawls :)

Answer 13

yeah just dont read my first remark or beyond:)

Answer 14

unless you want to kiss your teachers but:)

Answer 15

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

Answer 16

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

Answer 17

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

Answer 18

no that's ok lol

Answer 19

:)
