Polya created his famous four-step process for problem solving, which is used all over to aid people in problem solving:
Step 1: Understand the problem.
Step 2: Devise a plan (translate).
Step 3: Carry out the plan (solve).
Step 4: Look back (check and interpret​

Step-by-step explanation:

Step 1:

x - > number of Avocado

y -> number of melon

Step 2:

x ≤ 3y

x +  y ≥ 20

Step 3:

x + y≥ 20

     y ≥ -x + 20

Step 4:

( 1 , 20)

x ≤ 3y               ; y≥ -x + 20

1 ≤ 3*20          ;  20 ≥ -1 + 20

1 ≤ 60              ; 20 ≥ 19
