albeit fractions are involved...make it an integer problem
|Multiplying thru by 20so as all denominators = 1
64 + 15n = 150
15n = 86
n = 86/15 0r 5 11/15
.....
5n - 3 = n/3 + 67
15n - 9 = n = 201
14n = 210
n = 210/14 = 30/2 = 15
......
6n - 12 = n + 13
5n = 25
n = 5
....
n + n/4 = 60
4n + n = 240
5n = 240
n = 48
Two parts are 12 and 48
....
4n - n = 42
3n = 42
n = 14
two numbers are 14 and 56
and..
56 -14 = 42
