Question 145708: |3x+2|-2=4x+1
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! |3x+2|-2=4x+1
Rewrite:
|3x+2| = 4x+3
-----------------
Interpret:
If x > -2/3, 3x+2 = 4x+3
x = -1
Not a solution because -1 is not greater than -2/3
-----------------------
If x < -2/3
3x+2 = -(4x+3)
3x+2 = -4x-3
7x = -5
x = -5/7
Valid solution because -5/7 is less than -2/3
