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?

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

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

-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!
