Can someone help me with this please? The sum of the four numbers is 64. Now the first number plus three equals the second number minus 3, which in turn equals 3 times the third number, and this, in turn, equals the fourth number divided by 3. What is the difference between the largest and the smallest of the original numbers?

Final answer:

After creating and solving a system of algebraic equations based on the conditions of the problem, we determine that the difference between the largest and smallest original numbers is 33.

Step-by-step explanation:

The problem presents a system of equations that can be solved using algebra. Let's denote the four numbers as A, B, C, and D. The conditions given are:

  • A + B + C + D = 64 (The sum of the four numbers is 64)
  • A + 3 = B - 3 (The first number plus three equals the second number minus 3)
  • B - 3 = 3C (Which in turn equals 3 times the third number)
  • 3C = D / 3 (This, in turn, equals the fourth number divided by 3)

We can solve for one variable in terms of another and substitute into the equations step by step. Firstly, solve the second condition: A = B - 6. Substituting A in the first equation, we have:

B - 6 + B + 3C + D = 64

From the third and fourth conditions, we know B - 3 = 3C, which implies B = 3C + 3, and 3C = D / 3, which means D = 9C. Substituting these into our equation:

(3C + 3) - 6 + (3C + 3) + 3C + 9C = 64

Simplifying this gives us 3C + 3 - 6 + 3C + 3 + 3C + 9C = 64

Combining like terms, we find C = 5. Using C to solve for B, A, and D, we get B = 18, A = 12, and D = 45. The difference between the largest and smallest of the original numbers is D - A which is 45 - 12 = 33.
