Question 946357
Let n = larger number and
let m = smaller number
If I read the question correctly we have two equations;
(1) n = 4m - 1 and
(2) m = n - 3
Agree?
Assuming you do, put m of (2) into (1) and get
(3) n = 4*(n-3) - 1 or
(4) n = 4n - 12 - 1 or
(5) 3n = 13 or
(6) n = 13/3
Now put n of (6) into (2) and get
(7) m = 13/3 -  3 or
(8) m = 4/3
Check the answer with (1).
Is (13/3 = 4*4/3 - 1)?
Is (13/3 = 16/3 - 3/3)?
Is (13/3 = 13/3)? Yes
Answer: The larger number is 13/3
