In order to solve the equation -3x - 6 = 5, the first step is to: add 6 to both sides divide by 5 on both sides subtract 6 from both sides multiply by 5 on both sides

OpenStudy (ja1):

Well we need to isolate the variable.

OpenStudy (ja1):

So we need to get rid of the 6

OpenStudy (ja1):

How can we undo subtraction?

OpenStudy (ja1):

@SWAG to get rid of subtraction we do the inverse operation, so what is the opposite of subtraction?

OpenStudy (swag):

addition

OpenStudy (ja1):

exactly, so to get rid of -6 we do what?

OpenStudy (swag):

add?

OpenStudy (ja1):

Exactly, so if you add ? you cancel out -6 :)

OpenStudy (swag):

so its A

OpenStudy (ja1):

Yes, what you do to one side you do to both :)

OpenStudy (uri):
