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

Mar 28, 2018

$6 x + y - 9$

#### Explanation:

$2 x + y - \left(9 - 4 x\right)$

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:
$2 x + y - 9 + 4 x$

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

That is also the most simplified expression.

Hope this helps!
