Answer 9

But how do i count out 6a-12+4a-8? Is it 2a+4?

Answer 10

It's not 2a+4

Answer 11

no.. think again.. try to separate out variables keeping in mind the signs

Answer 12

Is it 10a-20?

Answer 13

Yup

Answer 14

Don't guess change $$6a-12+4a-8$$ into $$6a +(-12) + 4a +(-8)$$ now use the commutative property of addition to move like terms together, then simplify

Answer 15

recall: $$a-b= a+(-b)$$

Answer 16

To subtract b, add the opposite of b.

Answer 17

Is the answer 10a-20? or 10a+20?

Answer 18
