[+1] - fresco - 02/12/2009That's not an "equation". It's an "expression" or an arbitrary "identity" when you done the tidying up.
[+1] - BarbieQPickle - 02/12/2009Here you go: 4a+7bc-9b-6c-(3bc+2a+12c-b)= 4a+7bc-9b-6c-3bc-2a-12c+b= 2a+4bc-8b-18c
[+1] - sullyfish6 - 02/12/2009and reduced down (divided by 2) to lowest term: a+2bc-4b-9c
[+1] - fresco - 02/13/2009No you can't reduce it because its not an equation. You can only [i]factorise [/i]it e.g 2(a+2bc-4b-9c) or 2(a + 2b(c-2) -9c)
[+1] - BarbieQPickle - 02/13/2009yeah, why would you 'reduce down and divide by two'. It's a basic problem, combine like terms, simplify.

No you can't reduce it because its not an equation. You can only factorise it
e.g 2(a+2bc-4b-9c) or 2(a + 2b(c-2) -9c)
