Given | 2a-1 | + | 3B + 1 | + | 4C + 8 | = 0, find the values of a, B and C

Given | 2a-1 | + | 3B + 1 | + | 4C + 8 | = 0, find the values of a, B and C

Because after adding the absolute value sign, they are all non negative numbers, and the sum of the three is equal to 0, then they must all be 0
So it's easy to get
a=1/2 b=-1/3 c=-2
