The answer is 21 because times the bottom and top by 3 and 2 x 3 is 6 as there are 6 red pencils and 7 x 3 is 21.

Answer:
- 20 -5k = 4
- the LCM of the denominators is 10
Step-by-step explanation:
I find it convenient to do the problem in the reverse order: find the LCM, then distribute. That way, I'm not distributing a fraction.
The LCM of 2 and 5 is their product: 2·5 = 10. Multiplying the equation by 10 gives ...
5(4 -k) = 4
Now, distributing, we get ...
20 -5k = 4
If your trying to get Y=mx + b the answer would be 1. Y= x+4 2. Y= -1/3x + 4/3
