please help

can anyone help?

@AliSurfCat ok?

I really dont know

what is a equal to? according to the second equation

thats the thing I dont know:(

if i show you this, z = 10, what is z equal to?

10

perfect, now if i show you this, a = b − 2, what is a equal to?

a equals 4

a equals b - 2

and be equals 6

no, a equals b - 2

okay

ok lets make sure you understand this, if i show you j = 5i +z - 2, what is j equal to?

5i +z - 2

perfect :)

ok back to your question, so we know a is equal to b - 2

ok, b-2 − 3b = 4

perfect :)

now can you solve for b? with that equation b -2 -3b = 4

cna you help me on this one?

sure

how can i get rid of the -2 on the left side?

ok

what happens if we add 2 on both sides of the equation, what do you get?

you get 6

i get 6 on the right hand side of the equals sign but what about on the left side?

b - 2 + 2 - 3b = 4 + 2
b - 2 + 2 - 3b = 6

hey I have a few minutes left to turn this in please help

i am helping, if you just want the answer, i cant do that

I dont but think it is A

good luck bud

ok well thanks

if you change your mind and want to keep working through it let me know

I do :)

b-4-3b=6

close, but
-2 + 2 is not equal to -4

ohhh sorry got a little confused

ok so -2 + 2 = what?

it eaquals 0

perfect,
now we have
b + 0 - 3b=6
which equals
b - 3b = 6

can you simplify b - 3b = 6 by combining the b terms?

how do I do that

if i have 1b and i take away 3b's how many b's do i have?

do I just do 3b=6???

1b - 3b

--2b

correct

so we are almost done
we have
-2b = 6, now how can you get b by itself?

how can we get rid of the -2?

turn it into a 1

by adding 2 on both sides

by dividing both sides by -2

yes thats what I meant lol

-2/-2 = 1
so
(-2b)/-2 = 6/(-2)
1b = 6/(-2)
b = 6 / (-2)

so what is 6 / (-2),
6 divided by -2

-3

which one is it?

so it is D?

correct :)

yay thanks so much

I do

good :)

have a good day

you too

nice to see too much long conversation in such a simple question
