will medal asap

OpenStudy (rushwr):

The question ?

OpenStudy (anonymous):

4(y-1)+8-2y+20

OpenStudy (anonymous):

i think i understand a little more

OpenStudy (rushwr):

Is it the complete question

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

it is olmost like the frist one

OpenStudy (rushwr):

yeah go ahead, try and show me your work !

OpenStudy (anonymous):

ok so frist u do is 4*1=4

OpenStudy (rushwr):

okai

OpenStudy (madhu.mukherjee.946):

is this simple solve?

OpenStudy (anonymous):

then u 4+8

OpenStudy (rushwr):

yep/

OpenStudy (anonymous):

=12

OpenStudy (rushwr):

actually it's like this 4(y-1) = 4y-4 !

OpenStudy (anonymous):

so not 4*1

OpenStudy (madhu.mukherjee.946):

4y-4+8-2y+20 2y=-24 y=-12

OpenStudy (madhu.mukherjee.946):

am i correct?

OpenStudy (anonymous):

4y-4+0+8=8-2y=6

OpenStudy (rushwr):

@madhu.mukherjee.946 hey would you like to guide her little bit more. She is still small so if u don't mind please help her though!

OpenStudy (madhu.mukherjee.946):

@Rushwr sure!:)

OpenStudy (anonymous):

@Rushwr am i right

OpenStudy (madhu.mukherjee.946):

@limecake08 if you subtract 2y from 4y what do you get

OpenStudy (sohailiftikhar):

is this an equation ?

OpenStudy (sohailiftikhar):

where is the right hand side what is in right hand side huh ?

OpenStudy (madhu.mukherjee.946):

@limecake08 and if add 8 to 20 and suntract 4 from that then what do you get?

OpenStudy (anonymous):

can u please slow down i am panicking

OpenStudy (madhu.mukherjee.946):

ok first subtract 2y from 4y what do you get

OpenStudy (anonymous):

it does not go u have to do 4y-2y =2

OpenStudy (madhu.mukherjee.946):

yes it will give you 2y

OpenStudy (anonymous):

so next

OpenStudy (madhu.mukherjee.946):

do 20+8-4

OpenStudy (sohailiftikhar):

ok wait 4(y-1)+8-2y+20=0 is this a equation ?

OpenStudy (anonymous):

24

OpenStudy (madhu.mukherjee.946):

good

OpenStudy (madhu.mukherjee.946):

so now 2y+24=0 in an equation you always have the right hand side =0

OpenStudy (anonymous):

26

OpenStudy (sohailiftikhar):

who sais that ?

OpenStudy (sohailiftikhar):

said * that you always have a right hand side zero ?

OpenStudy (madhu.mukherjee.946):

no not 26,you cannot add 2y and 24 because 2y is a variable and 24 is a constant@limecake08

OpenStudy (madhu.mukherjee.946):

any term you see with an alphabet attached to it is known as a variable and any number is known as a constant

OpenStudy (madhu.mukherjee.946):

in an equation you always have to solve for that variable by keeping it in the left hand side and taking the constant to the right hand side

OpenStudy (madhu.mukherjee.946):

do you understand?

OpenStudy (anonymous):

no sorry

OpenStudy (anonymous):

did u say 11 was the aswer

OpenStudy (madhu.mukherjee.946):

which part do you not understand

OpenStudy (madhu.mukherjee.946):

no -12 is the answer

OpenStudy (anonymous):

can u right dow the work

OpenStudy (madhu.mukherjee.946):

okay

OpenStudy (madhu.mukherjee.946):

4y-4+8-2y+20=0 2y+24=0 2y=-24 y=-12

OpenStudy (anonymous):
