what is
4a+7bc-9b-6c-(3bc+2a+12c-b)=?
@parini13,
That's not an "equation". It's an "expression" or an arbitrary "identity" when you done the tidying up.
Here you go:
4a+7bc-9b-6c-(3bc+2a+12c-b)=
4a+7bc-9b-6c-3bc-2a-12c+b=
2a+4bc-8b-18c
and reduced down (divided by 2) to lowest term:
a+2bc-4b-9c
@sullyfish6,
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)
yeah, why would you 'reduce down and divide by two'. It's a basic problem, combine like terms, simplify.
Stumble It!
