I am thinking of two whole numbers. The larger number is 3 times the smaller number. If the difference between the two numbers is 72, what is the sum of the two numbers?
----------
Equation:
L = 3*S
L-S = 72
------
Substitute and solve for "S":
3S - S = = 72
2S = 72
S = 36 (smaller #)
-----
Solve for "L":
L = 3S = 3*36 = 108
========================
Sum = 36+108 = 144
========================
