Use the distributive property to remove the parentheses.

(-3+3u+x)(-2)

Using the distributive property, we distribute -2 to each term inside the parentheses:

-2 (-3) + (-2)(3u) + (-2)(x)

This simplifies to:
6 - 6u - 2x

To remove the parentheses using the distributive property, you need to distribute the -2 to each term inside the parentheses.

(-3+3u+x)(-2) = -2*(-3) + -2*(3u) + -2*(x)

Let's simplify each term:

-2*(-3) = 6
-2*(3u) = -6u
-2*(x) = -2x

Therefore, when we remove the parentheses using the distributive property, we get:

(-3+3u+x)(-2) = 6 - 6u - 2x

To remove the parentheses using the distributive property, you need to distribute the -2 to each term inside the parentheses.

1. Multiply -2 with -3: -2 * -3 = 6
2. Multiply -2 with 3u: -2 * 3u = -6u
3. Multiply -2 with x: -2 * x = -2x

After distributing -2 to each term inside the parentheses, you'll get:

6 + (-6u) + (-2x)

Simplifying the expression further, you can combine like terms:

6 - 6u - 2x
