Answer:
Option C is correct.
2d -2e
Step-by-step explanation:
Simplify: [tex]17d-5e + 3e -15d[/tex]
Like terms are those terms which have same variable to the same power.
Combine like terms of variable d first;
[tex](17d-15d)-5e + 3e[/tex]
Simplify:
[tex]2d-5e + 3e[/tex]
Now, combine like terms of variable e we have;
[tex]2d-2e[/tex]
therefore, the simplified form of [tex]17d-5e + 3e -15d[/tex] is, 2d - 2e
