I have to solve the equation: |12x -9| = |3 -4x| +2x -1(adsbygoogle = window.adsbygoogle || []).push({});

I was wondering if it's supposed to be like:

12x -9 = 3 -4x +2x -1 and -12x +9 = 3 -4x +2x -1 ?

Or am I supposed to consider the positive and negative of 3 -4x also?

I didn't attend lessons for this and I know little about modulus functions. :/
