Simplifying Algebraic Expression

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!

    Your answer isn't simplified.

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

    -6 - 9x + x - 5

    -8x - 11

    This 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.

    No. You didn't simplify.

    -3 (2 + 3x) + x - 5
    -6 -9x + x -5

    Combine like terms, then you are done.

    Joey is right you suppose to do the combine like terms at the end, but you simplify thought.

    Thank You Ms. Sue.
