Answer:
Jenny has 4 pencils.
Step-by-step explanation:
Let
Jenny has pencils = x
Arthur has pencils = 5x+6 (Arthur has 6 more than 5 times the number of pencils as Jenny. )
Total pencils = 30
We need to find how many pencils does Jenny have.
We basically can write the equation:
Total pencils = Jenny pencils + Arthur pencils
Putting values and solving to find value of x:

So, we have value of x = 4
Now, finding number of Jenny pencils:
Jenny has pencils = x = 4
Therefore, Jenny has 4 pencils.
