In working with Algebra I am doing expression simplfication
In doing the following I am getting a little confused
6a-3b-2a-6b=4a-9b
=-5
6a(minus)2a I understand because I see the (-) minus sign
Now how do I know
3b is supposed to plus(+) 6b???
I dont see a plus sign anywhere
That is ofcourse without figuring lt out from the outcome
Thanks in advanced
