# How do you simplify 10-(2y-6)-y?

Apr 17, 2018

$16 - 3 y$

#### Explanation:

Look at the parts individually, there is $10$, $- \left(2 y - 6\right)$ and $- y$. Breaking this down can help.

Looking at $- \left(2 y - 6\right)$:

You multiply everything inside the bracket by $- 1$. It may only look like $-$ but there is a $1$ there. Just like $y$ is actually $1 y$.

$- 1 \text{ x } 2 y = - 2 y$
$- 1 \text{ x } - 6 = 6$ ($- \text{ x } - = +$)

So now we have,
$10 - 2 y + 6 - y$

This can be simplified,

$10 + 6 = 16$
$- 2 y - y = - 3 y$

Therefore, it is simplified to just:
$16 - 3 y$
