Answer:
If there is "p" pounds of peanuts and "m" pounds of '20% peanuts and 80% almonds' mixture, then, we can get the following equations,
p + m = 10 -----------(1) and
4m/5 = 4 ------------(2)
whose solution is 5 lb peanuts and 5 lb mixture.
Step-by-step explanation:
In the mixture which Delaney wants to make there would be
 lb
 lb 
= 6 lb of peanuts
So, there will be (10 - 6) lb  
= 4 lb of almonds
If  Delaney has "p" pounds of peanuts and "m" pounds of the '20% peanuts and 80% almonds' mixture, then according to the question,
p + m = 10 -----------(1) and
4m/5 = 4 ------------(2)
So, from (2), 
m = 5 --------------(3)
So, from (1) and (3) , 
p = (10 - 5) = 5
