Answer:

  • The smaller number is 9 and the greater number is 52.

Explanation:

1. Name the smaller number x and the greater number y

2. One number is 43 greater than the other:

  • y - x = 43    [equation 1]

3. If the greater numbrer is divided by the smaller, the quotient is 5 and the remainder is 7:

  • y = 5x + 7    [equation 2]

4. Substitute y into the equation 1, to find x:

  • 5x + 7 - x = 43
  • 4x = 43 - 7
  • 4x = 36
  • x = 36 / 4
  • x = 9

5. Substitute x = 9 into the equation 2, to find y:

  • y = 5(9) + 7 = 45 + 7 = 52
