Simplify The following equations
(This is algebra, so PLEASE, only answer if you KNOW FOR SURE, thank you)

3a+7b+2c-a-4b

-8a-b-(-6c)-2a-b-5c

b-4c+3a-c-9b-4a

Sagot :

apologiabiology
mostly collect like terms
use associative property which is
(a+b)+c=a+(b+c)
also -a+b-c=(-a)+(b)+(-c) so you can move them around
and remember that:
you just use a general rule
x+x=2x
x^2+x^2=2x^2
3xy4xy=7xy
3x+4x^2=3x+4x^2
you can only add like terms( like terms are terms that are same name like x or y are differnt, and like terms have same power exg x^2 and x^3 and x^1/2 and such

I will oly put the naswers because I don't have much time

first one: 2a+3b+2c

second one: remember that -(-6c)=+6c so the answer is c-10a-2b

third one: -a-8b-5c
