Answer:

[tex]3ax-by+c[/tex]

a is the correct option.

Step-by-step explanation:

We have to find the sum of the polynomials ax + by + c, 2ax - 3by + c, and by - c .

Writing these polynomial in sum form

[tex]ax+by+c+2ax-3by+c+by-c[/tex]

Group the like terms, we get

[tex](ax+2ax)+(by-3by+by)+(c+c-c)[/tex]

Combine the like terms, we get

[tex]3ax-by+c[/tex]

a is the correct option.
