Question

How do you simplify 3(5 - 3x + 10y - 6z)

Answer 1

You would take the number outside of the parentheses and multiply it to the numbers inside. The answer would be
15-9x+30y-18z

Answer 2

Since you can't simplify or combine any of the values inside the parenthesis, you'd use the distribution property to solve this:

15 - 9x + 30y - 18z

This would be the most simplified form.

Hope this helps!
