Let the two numbers be x and y. Half the difference between two numbers is 2, (x - y)/2 = 2 = x - y = 4
The sum of the greater number and twice the smaller number is 13. This gives x + 2*y = 13
Substitute x = 4 + y in x + 2y = 13
=> 4 + y + 2y = 13
=> 3y = 9
=> y = 3
x = 7
The two numbers are 3 and 7.

Let's say x=the greater number, and y=the smaller number.
So you have:
Solve for z.
Plug in 4 for z.
Then do this:
Plug in 3 for y.
So, x=7 and y=3
I hope this helps!
