Homework Help: Math-Distributive Property

Posted by Samantha on Friday, February 5, 2010 at 12:27pm.

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.

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

you missed a sign.

besides that you multiplied the first term incorrectly

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