(-5/2)x - 5 = -55

- anonymous

what is x

- Mehek14

\(-\dfrac{5}{2}x-5=-55\) ?

- anonymous

no only the 5 is negitve.

- Serenity74

Solve for X. Bring 5 to the other side.

- Mehek14

it's the same thing
\(-\dfrac{5}{2}x-5=-55\)
\(\dfrac{-5}{2}x-5=-55\)

- anonymous

the second on.

- Mehek14

first thing
-55 + 5 = ?

- Serenity74

Then in order to remove the fraction you multiply by the reciprocal.

- Serenity74

and bam you get the answer for X.

- DanJS

the 'whole' , quantity possibly

- anonymous

what is x?

- Serenity74

You would get a whole number even if you did the reciprocal....

- Mehek14

first
-55 + 5 = ?

- anonymous

-50

- DanJS

(-5/2) * ( x - 2 ) = -55
maybe

- Mehek14

\(\dfrac{-5}{2}=-50\)

- Serenity74

Wat are you doing @DanJS lol

- Mehek14

\(\dfrac{2}{-5}*-50\)

- Serenity74

The X is part of 5/2 it's not seperated lol.

- anonymous

20

- Serenity74

Ummmmm @Mehek14 dats a bit too complicated

- Mehek14

that's how you solve it @Serenity74

- Serenity74

I lied my bad

- Serenity74

I didn't that you reciprocal-ed it sorry!!!!

- anonymous

so the answer is 20?

- Mehek14

yup

- Serenity74

Yes the answer is 20 and @Mehek14 is correct.

- anonymous

thank you!

- Mehek14

2*-50 = -100
-100/-5 = +20

- DanJS

(-5/2) * ( x - 5 ) = -55
sorry the wording looked like that to me, multiplied by (x - 5), that gives
x=27 though

- anonymous

thank you!!

- Serenity74

Wait.

- anonymous

yes

- Serenity74

No it is 20

- DanJS

instead of multiplied by x - and take away a 5 , or something

- anonymous

@DanJS 27 is not an answer.

- DanJS

yeah , sorry

- anonymous

@Serenity74 thank you.

- anonymous

good bye and I might have more questions.

- 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

- Serenity74

- 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

multiplied by x minus 5 -- to me is (x - 5)

- Serenity74

Lol but you do get it right now right?

- DanJS

yes i know how to do the math, just the wording is different than i have seen, maybe

- Serenity74

Lol you don't have to be sorry about nothing lol, wordings tend to trip people off XD.

- Serenity74

Heyyyyyyy IK you know math lol you after all have 99 and I am just at 41 lol. No needa get defensive lol.

- Serenity74

- Serenity74

- DanJS

are you sure there isnt something between the 'X' and the 'minus'
like even a comma, or something

- Serenity74

- Serenity74

- DanJS

haha , you can get to 99, with medals from addition probs from 1st grade maybe in a long long time

- Serenity74

XD @DanJS I am here to get some Calculus practice actually but i DON'T SEE ANY CALCULUS!! GAH! XD
