Janice is thinking of two numbers. She says that two times the first number plus the second number is 48. In addition, the first number plus three times the second number is 54
------------
Equations::
2f + s = 48
f + 3s = 54
--------
Modify for elimination:
2f + s = 48
2f + 6s = 108
------
Subtract and solve for "s"::
5s = 60
second number = 12
---------
Solve for "f"::
f + 3s = 54
f + 3*12 = 54
first = 18
