9a+7=4a-33 Subract 7 both sides 9a+7=4a-33 -7 -7 ========= @ineedhelp1110

Ok so then you have 9a=4a-40. Then would you divide by 9?

OpenStudy (anonymous):

just gather all the a one side and all the number in the other side , the problem will be solved

OpenStudy (uri):

9a=4a-40. shift 4a no the right side 9a-4a=0

OpenStudy (uri):

5a=40*

OpenStudy (anonymous):

So with 9a=4a-40. You put it on the other side making it 5a=-40. Then divide by 5 to get a=-8?

OpenStudy (uri):

It's 9a-4a=-40* sorry typo

OpenStudy (uri):

then 5a=-40 a=-40/5=-8 yess!

OpenStudy (anonymous):
