help please will medal @kla01 @thebro55 @CritiC @NicholausBlackmon @TrapBoiTrynaEducaate @Michele_Laino @princeharryyy Which property of equality would be used to solve the equation -3x = 252? addition subtraction multipication division

OpenStudy (nicholausblackmon):

c

OpenStudy (nicholausblackmon):

you are multplying because x and negative 3 are so close together

OpenStudy (danjs):

divide by -3 OR Multiply by -1/3

OpenStudy (anonymous):

Multiplication

OpenStudy (anonymous):

Whoops sorry you would divide! -3x/-3 cancels it out so x=252/-3

OpenStudy (anonymous):

remember PEMDAS? in properties of equalities, it becomes SADMEP (point is it's reverse). So you use Addition/Subtraction property first. then multiplication/division property

OpenStudy (anonymous):

X X X X X X X

OpenStudy (nicholausblackmon):

SOLVE! OHHHH

OpenStudy (nicholausblackmon):

then it is division

OpenStudy (nicholausblackmon):

D

OpenStudy (danjs):

multiplication and division are the same process. Just as Addition and subtraction are the same process -3 = +(-3)

OpenStudy (anonymous):

i told you because you would divide by -3

OpenStudy (anonymous):

c or d
