You said x + 2/5 = 12
It might be easier to handle if we use the decimal for 2/5.
x + 0.4 = 12
Subtract 0.4 from each side: x = 11.6
That's all there is to it. I'm sorry I can't make it
more complicated for you.

Answer:
Jenny will knit 8 inches per each hour.
Step-by-step explanation:
First I know that 1 foot is 12 inches.
1/3 of 13 is 4.
1 hour is 60 minutes.
2/3 of 60 is 40.
so she knits 4 inches in 40 minutes.
We will now add 1/3 to both to see how many inches/feet she knits per hour/60 minutes.
Adding 1/3 to 2/3 of an hour will look like:
That equals 60/60 which is 1 hour.
Adding 1/3 to 1/3 of a foot will look like:

That equals 8/12, which is 8 inches in a foot.
This means that in one hour, Jenny will knit 8 inches of a foot.
