Question

Help!!
b-2+8b=32

Answer 1

Simplifying
B + -2 + 8b = 32

Reorder the terms:
-2 + B + 8b = 32

Solving
-2 + B + 8b = 32

Solving for variable 'B'.

Move all terms containing B to the left, all other terms to the right.

Add '2' to each side of the equation.
-2 + B + 2 + 8b = 32 + 2

Reorder the terms:
-2 + 2 + B + 8b = 32 + 2

Combine like terms: -2 + 2 = 0
0 + B + 8b = 32 + 2
B + 8b = 32 + 2

Combine like terms: 32 + 2 = 34
B + 8b = 34

Add '-8b' to each side of the equation.
B + 8b + -8b = 34 + -8b

Answer 2

is this helpful

Answer 3

not really..

Answer 4

i have 1 banana, i add 8 more bananas
how many bananas do i have?

Answer 12

9

Answer 13

b + 8b = ( 1 + 8 )b = 9b

Answer 14

Okay so I just simply do 1+8 to get
2+9b=32?

Answer 15

Yes

Answer 16

the method is called adding like terms
you can only do it if they share teh same variable

Answer 17

in this case, "b"

Answer 18

After all the math @skullpatrol I get 3.7 repeated

Answer 19

So that can't be right...

Answer 20

Colud you help me out with finishing it off?

Answer 21

$$\huge 2+9b=32$$

Subtract 2^ from both sides

Answer 22

@skullpatrol
the original problem
b-2+8b=32

Answer 23

somewhere, in the explanation, the -2 became positive

Answer 24

Oops...

:-/

So add 2 to both sides.

Answer 25

Okay so 34

Answer 26

That's what I had before @skullpatrol

Answer 27

So you get 9b = 34

Answer 28

$$\huge 9b=34$$

Answer 29

divide 9 by 34

Answer 30

other way around 34 by 9

Answer 31

and yes fractions of 9 will give a repeating decimal

Answer 32

Well yeah that's what I mean : P

Answer 33

^

Answer 34

So I need to round the decimal?

Answer 35

And would I have 3.8 or 4? If I did round.

Answer 36

Why not 34/9?

Answer 37

I'm a bit lost. Sorry.

Answer 38

Wait do you mean b=34/9?

Answer 39

Yes.

Answer 40

you can leave it as @skullpatrol put it
or simplify it into a mixed fraction
\[3 \frac{7}{9}\]
or write it

Answer 41

the dash mark ontop of the 7 denotes a repeating value

Answer 42

The answer was 34/9 thank you guys!

Answer 43

Thanks for trying to understand :-)

Answer 44

I'm going to close this question, but is it okay if I can have you on standby in case I need anything else? @skullpatrol

Answer 45

sure
