The sum of two numbers is equal to 31. The smaller is doubled. The larger is decreased by 11. The resulting numbers are equal. What is the number?
-------
Equations:
x + y = 31
(2x)= (y-11)
---------------
Substitute for "x" and solve for "y"::
(2(31-y)) = y-11
----
62-2y = y-11
3y = 73
------
y = 26 1/2
----
x = 31- 26 1/2 = 4.5
