Simplify by adding and subtracting like terms

[curelnew]

-5(y-6x-z) - (-3)(x-y+2) problem

This is how far I've got:
-5y+30x+5z - -3x+3y-6
Thanks

Don't forget the parenthesis

-5y+30x+5z - (-3x+3y-6)

This is fine so far, now distribute the negative to get rid of all parenthesis and combine like terms

-5(y - 6x - z) - (-3)(x - y + 2)

-5y + 30x + 5z - (-3x + 3y - 6) Keep these parentheses in place, until you're ready to subtract.

You properly distributed the factors of -5 and -3.

The red parentheses above show that each of the three terms inside are being subtracted.

In order to remove these parentheses, we need to change the sign on each of the three terms. (If you do not understand why, let us know.)

-5y + 30x + 5z + 3x - 3y + 6

Can you now finish by combing like-terms?

Thank you all sooo much!
