The sum of the numbers is 40. Their difference is 14. What are the numbers?​

--------------------------------

ANSWER: 27 and 13

---------------------------------

  • Formulate 2 equations.
  • Let the two numbers be X and Y.

X + Y = 40

X - Y = 14

  • Assume X > Y
  • Then, add the 2 equations together.

X + X + Y - Y = 40 + 14

2x = 54

  • Then, divide by 2.

x = 27

  • Therefore, X = 27
  • To get Y, subtract X to 14.

27 - 14 = 13

  • Therefore, Y = 13

---------------------------------

CHECK (you may check it on a piece of paper or on a calculator.)

  • 27 + 13 = 40
  • 27 - 13 = 14

---------------------------------

:D Hope this helps!
