Daughter has maths homework, here’s an example

a(x+b) = c

When asked for x I can quite easily work out that x = c/a – b

However we are also being asked for x = the rest of the equation above and below a single line

I’m stumped, please help – I’ve put numbers in, but still can’t get it.

Ta

x=(c-ab)/a

because b = ab/a, and you need to get both terms over common denominator, i.e. a.

🙂 I have not done maths in years, it comes flooding back…

” above and below a single line”

eh?

Mowgli understood the question Stoner – thanks Mowgli. Just need to check it to confirm

common denominator,

Mowgli understood the question Stoner

so do I now 😉

Yup, all works with numbers – cheers Mowgli

How did her date go?

curfew’d? 😉

Isn’t that something to do with Star Trek II, the genesis device and Bill Shatner shouting “Kaaaaaaaaaaahn!” 😀

Ha, nah. It’s an award winning free educational site, mainly maths and physics.
