then u 4+8
OpenStudy (rushwr):
yep/
OpenStudy (anonymous):
=12
OpenStudy (rushwr):

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!

@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?

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

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

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):

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):
thanks
