First you cross multiply.
2*(b-4)=6b
Then distribute the 2.
2b-8=6b
Minus 2b from each side.
-8=4b
Divide each side by 4.
-2=b
So -2 is your answer.

Answer:
7k
____________________________________________________
Step-by-step explanation:
We are trying to combine like terms with the expression: -k - ( - 8k)
We are pretty much solving it.
Solve:
-k - ( - 8k)
The "- ( -" turns into a plus sign.
So it would look like:
-k - -8k or -k + 8k
Now, you would finish solving
-k + 8k = 7k

Hope this helped
18 would be the 7th so... hope it helps
Answer: f = 2/5 (0.4)
Step-by-step explanation:
1. Re-order terms so constants are on the left
f x 5 = 2 OR f(5)=2
2. Divide both sides by the same factor
f(5)=2 --> 5f/5 = 2/5
