-0.8b + 3.2b

4.1c - 0.1c

Combine those terms.
Answered by Reiny
We can only add "like" terms, so the b's go together and the c's go together

-0.8b + 4.1c -(-3.2b) - 0.1c
= -0.8b + 4.1c + 3.2b - 0.1c
= 3.2b -.8b + 4.1c - .1c
= 2.4b + 4c

And look at Reiny's post:

-0.8b + 4.1c -(-3.2b) - 0.1c
= -0.8b + 4.1c + 3.2b - 0.1c
= 3.2b -.8b + 4.1c - .1c
= 2.4b + 4c
Answered by Ms. Sue
B and C are the unknown numbers that are multiplied.

Example:

2x = 6
x = 3
