Using the Distributive Property & Combining Like Terms

Simplify:

-3 (2+3x) + x - 5

-3(2) + -3 (3x) + x - 5

Answer - 6 + -3(3x) + x - 5

Is the answer is correct??? I'm getting a bit confused and struggling a lot in this problem. Please help me!

**Ms. Sue**, Monday, October 15, 2012 at 7:50pmYour answer isn't simplified.

-3 (2+3x) + x - 5

-6 - 9x + x - 5

-8x - 11

**Brooke**, Monday, October 15, 2012 at 7:50pmThis is wrong. You were suppose to use the distributive property. Here, let me show you:

-3(2+3x)+x-5

= -6+-9x+ x-5

Then, you combine like-terms:

-6-5= -11

and then -9x+x= -8x

Thus, your answer should be -11-8x.

Hope I helped you a little bit.

**Joey**, Monday, October 15, 2012 at 7:52pmNo. You didn't simplify.

-3 (2 + 3x) + x - 5

-6 -9x + x -5

Combine like terms, then you are done.

**Laruen**, Monday, October 15, 2012 at 8:05pmJoey is right you suppose to do the combine like terms at the end, but you simplify thought.

Thank You Ms. Sue.
