4x=2 how do i solve?
OpenStudy (karatechopper):
divide by 4 on both sides
OpenStudy (karatechopper):
then simplify
myininaya (myininaya):
why can't i multiply both sides by 1/4 instead?
OpenStudy (karatechopper):
?????

OpenStudy (karatechopper):
sure
OpenStudy (karatechopper):
it could be!!!

i was thinking if anybody needed help tho....
OpenStudy (karatechopper):
uhhh algebra 2 comes after geometry?!?!
myininaya (myininaya):
you wanted to seem inviting
myininaya (myininaya):
algebra 2 comes after geometry?
OpenStudy (karatechopper):
yea i figured tht out

yep it does!!
myininaya (myininaya):
so you are talking about high school math
OpenStudy (karatechopper):
yea!!
myininaya (myininaya):
i remember this now
i think it was:
algebra 1
geometry
algebra 2
OpenStudy (karatechopper):
yes it is!

why don't you want a more challenging question?
like a calculus problem?
OpenStudy (karatechopper):
b/c i am in 7th grade learning Algebra 1
myininaya (myininaya):
oh i see
OpenStudy (karatechopper):
and i only kno algebra 1
myininaya (myininaya):
ok how do i solve
\[a^2+2ab+b^2+4a+4b=-4\]
for a+b?

OpenStudy (karatechopper):
so the equation has to equal a+b?
OpenStudy (anonymous):
here is an algebra question. prove A5 is simple
OpenStudy (karatechopper):
and what???? satellite? i am only gonna focus on one question at a time.... and tht is myin's
myininaya (myininaya):
\[a^2+2ab+b^2=(a+b)^2\]
\[4a+4b=4(a+b)\]
\[(a+b)^2+4(a+b)=-4\]
\[(a+b)^2+4(a+b)+4=0\]
OpenStudy (anonymous):
oh sorry. i will be quiet

now its ok cuz i dont get what the heck myin is sayin...
myininaya (myininaya):
lol
OpenStudy (karatechopper):
A5 IS A times 5
myininaya (myininaya):
asking you to solve that equation for a+b
OpenStudy (karatechopper):
ok now lemme get to work

myininaya (myininaya):
\[(a+b+2)^2=0\]
myininaya (myininaya):
\[a+b+2=0\]
you can solve this for a+b right?
OpenStudy (karatechopper):
yes!!! bbut i am on the first equation hold on
myininaya (myininaya):
ok
\[a+b=-2 :)\]
OpenStudy (karatechopper):
o wait i am confused!!!??? on first equation solve for me??? too many numbers...... the one u just said isa+b=-2

\[a^2+2ab+b^2+4a+4b=-4\]
\[(a+b)^2+4a+4b=-4\]
\[(a+b)^2+4(a+b)=-4\]
\[(a+b)^2+4(a+b)+4=0\]
----------------------------
remember how to factor \[u^2+4u+4\]
\[(u+2)^2\]
----------------------------
\[(a+b+2)^2=0\]
\[a+b+2=0 => a+b=-2\]
myininaya (myininaya):
do you guys factor in algebra 1?
solve equations in algebra 1?
OpenStudy (karatechopper):
we havent factored yet..
myininaya (myininaya):
oh then thats the problem
myininaya (myininaya):
ok try satellite's question whatever it was

i already did
OpenStudy (anonymous):
is solve for x:
\[2x-1=7\] and algebra 1 question?
and if so how about
\[ax+b-c\]?
OpenStudy (anonymous):
i meant
\[ax+b=c\]
OpenStudy (karatechopper):
x=4
c-b/a=x
myininaya (myininaya):
ax=c-b
x=(c-b)/a

ok so i guess that takes care of that kind. how about
\[9x+5=7x+1\] or
\[ac+b=cx+d\]
