4b+2a-c
Explanation:
b+3b+2a-c
=4b+2a-c
2a and c will be the same because their variables are not same. They are not like terms.
2a+4b-c
Combining like terms: 3b+b=4b
2a stays the same
-c stays the same
Since a and c does not match together they stay the same and not combine since they are not like terms.
