A number is 1/7 of another number. The difference of the numbers is 18 (Assume that you are subtracting the smaller number from the larger number.) Find the numbers

Respuesta :

The smaller number is 3. The larger number is 21. 

You can get this using the following system of equations and solving by any method. 

x - (1/7)y = 0
-x + y = 18
