You know B = 50

and that A + B = 80

So A should be easy.

Similarly for C

I'm back and I need to know how to get the value of A and C? What is the equation for getting it?

And that light sabre isn't just for show.

Tell your teachers I am watching them, closely.

Hey guys! I got it! Thanks again!
Will be posting for other horrid math problems soon! 👽

Teachers are always doing that. Trying to force someone to think. It is evil and soon will be outlawed.

She got what she wanted.  I think she'll be back next time her 'horrid' teachers set another nasty one.  (Don't forget; I know what an evil bunch they are smile

Bob, she skedoodled out of the forum.

I suspect three simultaneous equations is a bit tough for Abby.

Give her a year or two on the forum and she'll be fine. 

Hope you have got there now, Abby  smile


ps.  Now why didn't I think of that user name?  really cool.

Are you okay with those equations?

Ok weird but your solution has come up after I posted the remark.
Thank you.

2013-03-07 09:38:33

Can you solve the set of equations? Do you need help there?

Hi Admin Bob.  Sorry but the answer you posted was incomplete or blank  after "adding gives"... Which still left me pondering as how you got the values of A B and C. I'm still in Yr6 here in UK you see so I need a detailed solution. My Dad is helping me with this forum but unfortunately cannot help me with the math problems :-)

hi Abby ❤ Choco

Welcome to the forum.

I would do this:

adding gives

After which it should be easy enough to get A and C.

Cool user name by the way!  smile
