OpenStudy (anonymous):
-2h-3h=25
-5h=25
h=-5
OpenStudy (anonymous):
8h - 3h -10h = 25
=> -5h = 25
=> h = 25/(-5)
=> h = -5
OpenStudy (anonymous):
Thank you. But how did you get that answer?
OpenStudy (anonymous):
u didnt get the solution?
mean the simplifications?
OpenStudy (anonymous):
come to www.chatindia.co.in and i'll tell you there. due to this slow site i can't help you fast.

OpenStudy (anonymous):

OpenStudy (anonymous):
yea
OpenStudy (anonymous):

what does it give?
OpenStudy (anonymous):
oh on the left :)

-2
OpenStudy (anonymous):
-2h,right?
OpenStudy (anonymous):
yes
OpenStudy (anonymous):
now we have got one term involving h on the right side
shift it to left,u would have change in sign
OpenStudy (anonymous):
so it comes
-2h-3h=25
right?

OpenStudy (anonymous):
what about -2h=3h+25
OpenStudy (anonymous):
shift 3h to the left
OpenStudy (anonymous):
ok
OpenStudy (anonymous):
then -2h-3h=25
gives
-5h=25
ok?
OpenStudy (anonymous):
ok thanks :D

OpenStudy (anonymous):
so dividing both sides by -5,we get
h=-5 :)
OpenStudy (anonymous):
so i have another. i just want to get this stuff down. X)
OpenStudy (anonymous):
y+2(y-5)=2y+2
OpenStudy (anonymous):
oh sure
OpenStudy (anonymous):
y +2y-10=2y+2
got it?

OpenStudy (anonymous):
ya
OpenStudy (anonymous):
y+2y-2y=2+10
y=12
OpenStudy (anonymous):
again collecting the term involving y on one side,and constant on the other
OpenStudy (anonymous):
should i subtract 2y from the other side?
OpenStudy (anonymous):
from the right?

OpenStudy (anonymous):
yea
OpenStudy (anonymous):
well it would be cancelled out with +2y
OpenStudy (anonymous):
aren you supposed to cancle everything out?
OpenStudy (anonymous):
no
OpenStudy (anonymous):
ok do one thing u try a solution,i wanna check where r u facing the prob:)

OpenStudy (anonymous):
y=2+10y=12 ?I dont know :o
OpenStudy (anonymous):
no
solve the left side first n post it
OpenStudy (anonymous):
start from the begining?
OpenStudy (anonymous):
yup
OpenStudy (anonymous):
kk

OpenStudy (anonymous):
y^2-3 is the left side i got
OpenStudy (anonymous):
y+2(y-5) is the left side ,ok?
OpenStudy (anonymous):
2 is multiplied with both the terms in parenthesis
OpenStudy (anonymous):
n we get
y+2y-10
right?
OpenStudy (anonymous):
ok

OpenStudy (anonymous):
now first simplify it,n post
OpenStudy (anonymous):
the left?
OpenStudy (anonymous):
3y-10
OpenStudy (anonymous):
fine :)
OpenStudy (anonymous):
now whats on the right involving y?
shift it to the left, n post

3y-10+2y=2
OpenStudy (anonymous):
good show, simplify the term involving y n shift 10 on the right
OpenStudy (anonymous):
o o, when u shift 2y on the left, it becomes -2y
OpenStudy (anonymous):
5y=-8?
OpenStudy (anonymous):
nops

read my previous
OpenStudy (anonymous):
it must be 3y-2y+10=2,right?
OpenStudy (anonymous):
ya
OpenStudy (anonymous):
ah wrong me ...sorry
3y-2y-10=2
OpenStudy (anonymous):
that makes more sence!

:)
OpenStudy (anonymous):
now simplify it
OpenStudy (anonymous):
1y-10=2
OpenStudy (anonymous):
shift 10 to the right
OpenStudy (anonymous):
u get y=12 :)

iy=12
OpenStudy (anonymous):
1y=12
OpenStudy (anonymous):
1y=y?
OpenStudy (anonymous):
THEN Y=12 OH CAPS..
OpenStudy (anonymous):
u got it now?
