.
Solve the equation 3|4x+1|-4=2.
---------------------------------------------------
Re-write it as |4x+1| = = 2.
If |4x+1| >= 0, then |4x+1| = 4x+1, and the equation takes the form
4x+1 = 2.
Solve it:
4x = 2-1, 4x = 1, x = .
If |4x+1| < 0, then |4x+1| = -(4x+1), and the equation takes the form
-4x-1 = 2.
Solve it:
-4x = 2+1, 4x = -3, x = .
Check yourself that both solutions are correct.
Answer. x = and x = .
