-1=2k+5/-4-k
anonymous
  • anonymous
\[-1=\frac{2k+5}{-4-k}\] multiply both sides by \(-4-k\) and solve \[k+4=2k+5\]you good from there?
anonymous
  • anonymous
you can almost do it in your head subtract \(k\) and get \[4=k+5\] then subtract \(5\)

Okay then k is -1?
anonymous
  • anonymous
I don't know i i did the last one right. its -2+-3-7/2-k and i got k=-5. Am i right?
anonymous
  • anonymous
yeah it is \(k=-1\) and you can check that it works
anonymous
  • anonymous
I mean -2=-3-7/2-k
anonymous
  • anonymous
is the numerator really \(-3-7\)?
anonymous
  • anonymous
yes
anonymous
  • anonymous
i.e. \(-10\)
anonymous
  • anonymous
can you explain it?
anonymous
  • anonymous
so \[-2=\frac{-10}{2-k}\] or \[-2(2-k)=-10\] then \[-4+2k=-10\]
anonymous
  • anonymous
add 4 to both sides and get \(2k=-6\) and so \(k=-3\)
anonymous
  • anonymous
i take it we were solving \[-2=\frac{-3-7}{2-k}\] with no \(k\) up top, right?
anonymous
  • anonymous
yes
anonymous
  • anonymous
ok did you get all the steps? or would you like me to rewrite them?
anonymous
  • anonymous
I got it! Thanks!
