-------------------
Let the numbers be x and y:
EQUATIONS:
1st: x + y = 27
2nd:(1/2)x + (1/3)y = 11
-----------------
Rewrite:
Multiply thru 2nd by 6 and multiply 1st by 2 to get:
1st: 2x + 2y = 54
3rd: 3x + 2y = 66
---------------------------
Subtract 1st from 3rd to get:
x = 12
-----------
substitute into x+y = 27 to solve for y:
12 + y = 27
y = 15
