Math-Distributive Property

posted by .

Use the distributive property to simplify: 3(m-1)-(2m+1)How would you do this?

This is all I have 3m-1-2m+1 I don't know if that right or what to do from there. Your help is greatly appreciated.

  • Math-Distributive Property -

    not right. look at the second term:
    -(2m+1)=-2m-1

    you missed a sign.

  • Math-Distributive Property -

    besides that you multiplied the first term incorrectly

    3(m-1) is 3m-3 , and not 3m-1
