Answer 4

ok so you have to collect like terms, do you know what like terms are?

Answer 5

like -b and 2b

Answer 6

essentially the same pronumerals regardless of their coefficient can be added together and constants can add/subtract together.

yes exactly

Answer 7

e.g. 2b - b = b
technically there is meant to be a 1 in front of the b but we don't write it out

Answer 8

and for constants
e.g. 3 + 5 = 8

Answer 9

ok so do I just add all the like terms?

Answer 10

and that's my answer?

Answer 11

yep, you add the b's together, the x's together and the constant

Answer 12

Answer 13

Answer 14

yep that should be the correct answer
