The sum of two positive integers is 1,287. If the larger number is 9 1/2 more than 2 1/2 times the smaller number, what are the two numbers?
------
Equations:
a + b = 1287
a = (5/2)b + (19/2)
-----
Substitute for "a" and solve for "b":
(5/2)b + (19/2) + b = 1287
--------------------------------
5b + 19 + 2b = 2574
7b = 2555
b = 365
----
Solve for "a":
a + 365 = 1287
a = 922
--------------------
