Simplify -3[b-(-7)]

OpenStudy (tinylittlehelper):

So, what is in the way of [b-(-7)] ?

OpenStudy (anonymous):

The minus sign?

OpenStudy (tinylittlehelper):

Well, there is a -3 in the way. A multiplying -3. How do we get rid of a multiplying -3?

OpenStudy (anonymous):

distributive property

OpenStudy (tinylittlehelper):

Is the [] absolute value?

OpenStudy (anonymous):

?

OpenStudy (tinylittlehelper):

the brackets I wa jut wondering

OpenStudy (tinylittlehelper):

*was just

OpenStudy (anonymous):

no?

OpenStudy (anonymous):

I'm just confused with distributing the -3 to the -(-70

OpenStudy (anonymous):

(-7)*

OpenStudy (anonymous):

I need to finish this soon, so I can study it

OpenStudy (tinylittlehelper):

Oh, okay. Anyway, the distributive property would be: \[(-3*b)-(-3*(-7))\] But, to get rid of a multiplying -3, I'd do: |dw:1444957286845:dw|

OpenStudy (tinylittlehelper):

And so, try to solve the distributive property. -3 x b = -3b. Try to solve the other side of the equation.

OpenStudy (anonymous):

would the sign change to addition so it would be -3b+(-21)?

OpenStudy (tinylittlehelper):

No, it would stay the same. But good job for simplifying that side. I wish I could tell you that that was all, but that isn't completely simplified.

OpenStudy (anonymous):

i thought it was keep change change

OpenStudy (tinylittlehelper):

Oh yeah, the sign does change! I'm sorry.

OpenStudy (anonymous):

so is the answer -3b+(-21)?

OpenStudy (tinylittlehelper):

Yes. To completely simplify it, you don't have to add the plus sign. Sometimes, you actually helped me to help you. Lol Good job!

OpenStudy (anonymous):

thank you!

OpenStudy (anonymous):

can i ask you anything whenever i need to help? or do i need to pay from now on?

OpenStudy (tinylittlehelper):

No, you don't need to pay. Math in't my strong point, though, but I love to help with grammar. Also, you can close a question when you feel as if it is solved.

OpenStudy (anonymous):

ok well thanks for helping me
