Answer:
No.
Step-by-step explanation:
Let's start by simplifying the first expression:
[tex]8a-3b-(2a+4b)[/tex]
Remove the parentheses:
[tex]8a-3b-(2a)-(4b)\\8a-3b-2a-4b[/tex]
Combine like terms:
[tex]8a-2a-3b-4b\\6a-7b[/tex]
[tex]6a-7b\neq 6a+b[/tex] (Assuming that none of the variables are equivalent to 0)
