Solution

Let's solve this step by step:

  1. Let's assume the two numbers are x and y, where x is the greater number and y is the smaller number. According to the problem, the difference between the two numbers is 5. So, we can write this as:

    x - y = 5 -----(equation 1)

  2. The problem also states that six times the smaller number (6y) lacks by 6 from four times the greater number (4x). We can write this as:

    4x - 6y = 6 -----(equation 2)

  3. Now we have a system of two equations, and we can solve it. Let's multiply equation 1 by 6 and equation 2 by 1:

    6x - 6y = 30 -----(equation 3) 4x - 6y = 6 -----(equation 4)

  4. Subtract equation 4 from equation 3:

    (6x - 4x) = (30 - 6) 2x = 24 x = 24 / 2 x = 12

  5. Substitute x = 12 into equation 1:

    12 - y = 5 y = 12 - 5 y = 7

So, the two numbers are 12 and 7. Therefore, the correct answer is 12 & 7.
