Question

How do you simplify the expression `2x+y-(9-4x)`?

Answer 1

`6x+y-9`

Explanation:

`2x+y-(9-4x)`

We need to use the distributive property here. This is where the negative sign will multiply everything in the parenthesis. So the negative will apply to both the `9` and the `-4`.

This is what the new expression looks like:
`2x+y-9+4x`

Now we can simplify this by adding like terms, or `2x` and `4x`:
`6x+y-9`

That is also the most simplified expression.

Hope this helps!
