(-5/2)x - 5 = -55
anonymous
  • anonymous
what is x
Mehek14
  • Mehek14
\(-\dfrac{5}{2}x-5=-55\) ?
anonymous
  • anonymous
no only the 5 is negitve.
Serenity74
  • Serenity74
Solve for X. Bring 5 to the other side.
Mehek14
  • Mehek14
it's the same thing \(-\dfrac{5}{2}x-5=-55\) \(\dfrac{-5}{2}x-5=-55\)
anonymous
  • anonymous
the second on.
Mehek14
  • Mehek14
first thing -55 + 5 = ?
Serenity74
  • Serenity74
Then in order to remove the fraction you multiply by the reciprocal.
Serenity74
  • Serenity74
and bam you get the answer for X.
DanJS
  • DanJS
the 'whole' , quantity possibly
anonymous
  • anonymous
what is x?
Serenity74
  • Serenity74
You would get a whole number even if you did the reciprocal....
Mehek14
  • Mehek14
first -55 + 5 = ?
anonymous
  • anonymous
-50
DanJS
  • DanJS
(-5/2) * ( x - 2 ) = -55 maybe
Mehek14
  • Mehek14
\(\dfrac{-5}{2}=-50\)
Serenity74
  • Serenity74
Wat are you doing @DanJS lol
Mehek14
  • Mehek14
\(\dfrac{2}{-5}*-50\)
Serenity74
  • Serenity74
The X is part of 5/2 it's not seperated lol.
anonymous
  • anonymous
20
Serenity74
  • Serenity74
Ummmmm @Mehek14 dats a bit too complicated
Mehek14
  • Mehek14
that's how you solve it @Serenity74
Serenity74
  • Serenity74
I lied my bad
Serenity74
  • Serenity74
I didn't that you reciprocal-ed it sorry!!!!
anonymous
  • anonymous
so the answer is 20?
Mehek14
  • Mehek14
yup
Serenity74
  • Serenity74
Yes the answer is 20 and @Mehek14 is correct.
anonymous
  • anonymous
thank you!
Mehek14
  • Mehek14
2*-50 = -100 -100/-5 = +20
DanJS
  • DanJS
(-5/2) * ( x - 5 ) = -55 sorry the wording looked like that to me, multiplied by (x - 5), that gives x=27 though
anonymous
  • anonymous
thank you!!
Serenity74
  • Serenity74
Wait.
anonymous
  • anonymous
yes
Serenity74
  • Serenity74
No it is 20
DanJS
  • DanJS
instead of multiplied by x - and take away a 5 , or something
anonymous
  • anonymous
@DanJS 27 is not an answer.
DanJS
  • DanJS
yeah , sorry
anonymous
  • anonymous
@Serenity74 thank you.
anonymous
  • anonymous
good bye and I might have more questions.
Serenity74
  • Serenity74
Yes so you end up with -5/2x = -50 -5x = -50 (2) (since the two cancel out on the other side by multiplying it) then you get -5x = -100 x = -100/-5 = +20 (since negative * negative give you a positive answer) @DanJS

  • DanJS
right, the wording in the problem is goofy to me if the words had something like 'and take aqway 5' or 'then take 5 away', may be clearer the x - 5 sounds like a quantity to me, sorry bout that
DanJS
  • DanJS
multiplied by x minus 5 -- to me is (x - 5)
Serenity74
  • Serenity74
Lol but you do get it right now right?
DanJS
  • DanJS
yes i know how to do the math, just the wording is different than i have seen, maybe
