Question

Are the expressions 8a - 3b - (2a + 4b) and 6a + b equivalent?

Answer 1

Answer:

No.

Step-by-step explanation:

Let's start by simplifying the first expression:

$8a-3b-(2a+4b)$

Remove the parentheses:

$8a-3b-(2a)-(4b)\\8a-3b-2a-4b$

Combine like terms:

$8a-2a-3b-4b\\6a-7b$

$6a-7b\neq 6a+b$ (Assuming that none of the variables are equivalent to 0)
