Question

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

Answer 1

No.

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\\eq 6a+b` (Assuming that none of the variables are equivalent to 0)
