Equation

so here we solve this , ok !

10(11n+5)= -10n-10+90n

110n+50= -10n+90n-10         ( here in the first part we have multiplied 10 and 11n and 10 and 5 ! in the second we have just arranged the same values together )

110n+50=80n-10   ( here we have just minussed the 10n and 90n as u can see in the 2nd part)

110n-80n=-50-10    (here we have arranged the same values together )

30n=-60     ( here we have minussed in the 1st part and added in the second )

n=-60/30  (divide 60 and 30 gives -2 )

n=-2   So ur answer or n is -2 ! 

Problem has already solved this one for you!

If you are wondering how you can make sure that your answer is right, you can always check your answer by putting the number that n equals in the original equation.

Let's put rosala's n = -2 in to make sure it works!

10(11n+5)=-10n-10+90n

10(11(-2)+5)=-10(-2)-10+90(-2)

10((-22)+5) = (+20)-10+(-180)

10(-17) = 20-10-180

-170 = 10-180

-170 = -170

This is a true statement, -170 does equal -170, so we know the answer is right.

Anyway, hope this helped.

that was good NinjaDevo 1 i also knew that way but im happy it helped kaylaaa ! but i have a doubt in my mind , do u think that might be rosalas answer wrong so why not check it ! if u r not thinking this this then its good because its just a doubt in my mind ! lol! but pls tell me what u meant about me ! for it can be clear !

Good job by both of you.....I think NinjaDevo was just checking your excellent answer, rosala, to see that it "worked"...and it did!!

Thumbs Up and Points to both of you !!!

No, I didn't doubt your answer rosala. I just wanted to show that you could check your answers pretty easily in problems like this. Your a great mathematician, rosala!

sorry guys but im workin' on a hard access class & yall are my only hope to help me pass. lol 

For each of the following problems, set up an equation and solve.  Write a sentence explaining your answer.

1.       Renee wants to take her daughter and some of her daughter’s friends to the movies.  A movie ticket is $8.  Renee budgets $50.  How many of her daughter’s friends can go to the movies?
        

2.       A plumber charges a flat rate of $50 and $25 an hour for the work.  The plumber received $150 for his services.  How many hours did the plumber work?
        

ok! thanks for the reply NinjaDevo ! i also didnt took this thing too seriously , but after reading ur answer i just had a lil thought and had an idea to share to u about this , i also know u had no bad intention but just wanted to cool down my thought for it to know the truth and so asked u ! by the way thanks for the point CPhill ! and a thumbs up from me NinjaDevo for the great answer ! and thanks for the compliment NinjaDevo , i really liked it! lol!

kaylaaa , i think that u should also give these a try and so on seeing ur answer we can tell u or help u correcting it becoz if we just give u the answer what will u learn ! so dont worry for the answer is correct or wrong just post what u know and ull be helped !

Problem answered this question for you correctly a little while ago on an earlier post. One that you stuffed up by putting a second nonsense question in.

If you didnt understand you should have said so. Instead you gave problem thumbs down for helping you and reposted your question.  

You are a very rude girl.
