For what it's worth, (not much you will probably say)
I can show you how to solve it using a graphing calc like a Ti83
:
The problems states:
1000A + B = 3(AB)
:
B - 3AB = - 1000A
B(1-3A) = - 1000A
B = -1000A/(1-3A)
:
enter into calc: y = -1000x/(1-3x): use the x,y table
The first integers that satisfy the requirements are:
A = 167, B= 334
3(167*334) = 167334
