x / -3 = 7 x / -3 = 7 @Mathematics

OpenStudy (anonymous):

isolate x by undoing the division (multiply by -3) what you do to one side you must to the other so x= 7*-3=-21

OpenStudy (anonymous):

and then..

OpenStudy (anonymous):

thats the answer? is that what your asking?

OpenStudy (anonymous):

and how'd you get 7 in the front?

OpenStudy (anonymous):

it doenst matter if its 7times -3 or -3 times 7 they both equal -21

OpenStudy (anonymous):

if it asks to solve x the answer must be x=something put variables one side and numbers on the other

OpenStudy (anonymous):

okay, thanks! :)

OpenStudy (anonymous):

and how'd you get -21?

OpenStudy (anonymous):

cause don't you need to multiply by the same number?

OpenStudy (anonymous):

no lets start over

OpenStudy (anonymous):
