    solve or simplify?

    solve means we have an equation or inequality

    -4-9=-(4+9)=-13 so n-4-9=n-13

    Yeah I would assume simplification . . . so just add the regular numbers like freckles did. There's only one variable. Any further simplification would require a given solution.

    I have to ask @beckyg111 did you mean n-4=9

    is that suppose to be -3x+6=-3x+2+4 ?

    are you sure its not like n(-4 - 9)?

    no. you bring the -3 and the x down so that would look like this. -3x. The 3 is negative and the 6 is positive so the result will be negative...i think then all you do is multiply 6 and 3 (my mistake its not 24 its 18) So then you bring the -3x and add the 18 -3x 18

    so you mean -3(x+6) which when using distributive property gives -3(x)+(-3)(6) -3x+(-18) -3x-18

    I guess but i have to show my work and i have to do it the way my teacher showed me http://easyk12.blogspot.com/2011/10/multiplication-rainbow-method.html

    Yeah . . . The solution -3x - 18 does match with that.

    I honestly don't think it is you. I think something is missing... because the site becky linked us too shows something completely different than problems expressed here.

    actually she wrote -3x(+6) which is just really -3x(6) again x is a multiplication symbol this is still -18 though
