Just need help setting up the problem

Question

The sum of two numbers is 75. The difference of one of them and twice the other one is 0. Find both numbers.

Answer 1

Let n be the larger number, and let m be the smaller number.  Then from the given information,

 

n + m = 75  [The sum of two numbers is 75]

n - 2m = 0   [The difference of one of them and twice the other one is 0]

 

This is the setup of the problem.  You need to solve the system of equations:

 

n + m = 75

n - 2m = 0

 

Can you take it from here?
