The larger of two numbers is twice the smaller number. If 12 is subtracted from the larger number, the result is 7 more than the smaller number. Find the numbers.

Answer

Let the smaller number be x and the larger number be y.

  1. According to the problem, the larger number is twice the smaller number: y = 2x.
  2. If 12 is subtracted from the larger number, the result is 7 more than the smaller number: y - 12 = x + 7.

Substitute y = 2x into the second equation:

2x - 12 = x + 7

Solve for x:

  1. Subtract x from both sides: x - 12 = 7
  2. Add 12 to both sides: x = 19

Now, find y using y = 2x:

y = 2(19) = 38

The numbers are 19 and 38.
