|3w-1| = |3w|

or

abs(3w-1) - abs(3w)

I know you can use a calculator and find the answer easily, but we're supposed to know how to do this without a calculator.

A. (3w-1) = (3w)

B (3w-1) = -(3w)

C. -(3w-1) = (3w)

D. -3(w-1) = -(3w)

A and D are the same, use A

B and C are the same, use B

so

A:

3w-1 = 3w

0 * w = 1 no solution possible

B:

3 w - 1 = - 3 w

6 w = 1

w = 1/6
