Question 361043: The sum of twice a first number and seven times a second number is 66. If the second number is subtracted seven times from the first number the result is 27. Find the numbers. Answer by robertb(5830) (Show Source):
You can put this solution on YOUR website! 2f + 7s = 66
7f - s = 27.
Multiply the bottom equation by 7, and then add corresponding sides with the top equation. We get 51f = 255, or
f = 5. Then s = 7*5 - 27 = 35 - 27 = 8.
