–6p – 21 = 3p – 12

OpenStudy (petiteme):

Transpose -21 and 3p to the opposite side. It'll be -6p - 3p = 21 - 12

OpenStudy (petiteme):

Then compute ;3

OpenStudy (anonymous):

so its 3?

OpenStudy (petiteme):

No. Did you try to compute it step by step?

OpenStudy (anonymous):

Yeah -3?

OpenStudy (petiteme):

From -6p - 3p = 21 - 12 Add -6 and -3 What's the answer?

OpenStudy (anonymous):

9 but thats not one of the options for an answer...

OpenStudy (petiteme):

It's not 9. Negative plus negative will always be negative, so it's -9p

OpenStudy (anonymous):

But thats not an answer..

OpenStudy (petiteme):

From there, -9p = 21 - 12

OpenStudy (petiteme):

Do it step by step and not just get the answer. That's why i'm here to help you

OpenStudy (anonymous):

Okay so -9 added to 12?

OpenStudy (petiteme):

No why added? I put an equal sign. It should be like this: -9p = 21 - 12

OpenStudy (anonymous):

what do you do im confused :(

OpenStudy (petiteme):

Let's start again :) From your equation: –6p – 21 = 3p – 12

OpenStudy (petiteme):

-6p - 21 = 3p - 12

OpenStudy (anonymous):

Okay

OpenStudy (petiteme):

Transpose -21 to the other side first. Give me your equation

OpenStudy (petiteme):

Transpose means you'll transfer it to the other side of the equation and if you transpose, the sign will change to. For example, a positive will be a negative

OpenStudy (anonymous):

-1 is the answer thanks!

OpenStudy (petiteme):

I'm glad you got it :)

OpenStudy (anonymous):

hey help me with one more?

OpenStudy (petiteme):

Yeah sure. Close this then post another one and tag me

OpenStudy (anonymous):

OpenStudy (petiteme):
