# How do you simplify (- 6x + 1) - ( - 3x + 1)?

$- 3 x$

#### Explanation:

$\left(- 6 x + 1\right) - \left(- 3 x + 1\right)$

When multiplying a negative by a negative, your negative automatically becomes a positive.

Also, it helps if you imagine that in between two problems (basically in between the parentheses) and behind the sign there is always a $1$ (of course, if there IS a number there, the number shown would be used instead of $1$).

You should always remember to ONLY add numbers together if they have something in common.

Anyways, due to this, your expression should now look like this;

$- 6 x + 1 + 3 x - 1$

The ones would be canceled out and you would be left with

$- 6 x + 3 x$

which would then equal

$- 3 x$

(Just think of it as $6 - 3$, but remember that in the actual expression, $6$ is smaller because it is a negative).
