5 = –(–z + 3)

OpenStudy (jango_in_dtown):

when you have -, change the signs of everything inside the brackets so 5=z-3 now add 3 on both sides and you have the answer

@leothelion

OpenStudy (anonymous):

thx

OpenStudy (anonymous):

i dont get it

OpenStudy (lochana):

what do want to do with it. Do you want the value of Z?

OpenStudy (anonymous):

yes i should have explained better

OpenStudy (jango_in_dtown):

-(a+b)=-a-b

OpenStudy (lochana):

@jango_IN_DTOWN will explain to you:)

OpenStudy (jango_in_dtown):

so -(-z+3)=-(-z)-3=z-3

OpenStudy (anonymous):

i get that part its just distrbuting the 3

OpenStudy (jango_in_dtown):

when you add 3 on both sides, you have 5+3=z-3+3 or 8=z i.e. z=8 since -3+3=0

OpenStudy (anonymous):

ok i get it but what about the 6

OpenStudy (jango_in_dtown):

there is no six

OpenStudy (jango_in_dtown):

-a+a=0 so -3+3=0

OpenStudy (anonymous):

3+3 is irrelevent then right

OpenStudy (jango_in_dtown):

its not 3+3 its -3+3

OpenStudy (anonymous):

oh so its 0 ok i get it thx bro

OpenStudy (jango_in_dtown):

the right hand side was z-3 when you add 3 it becomes z-3+3=z
