I3x+4I The I is absolute value sign. What do I do? Thanks
_____ = 2
I2x+4I
----------------
You have to examine the possibilities:
If 3x+4 and 2x+4 are both positive your problem becomes:
(3x+4)/(2x+4) = 2
3x+4 = 4x+8
x = -4
Test this value: |-12+4|/|-8+4|=2
True
------------
If 3x+4 is negative and 2x+4 is positive you get:
-(3x+4)/(2x+4) = 2
-3x-4 = 4x+8
7x = -12
x = -12/7
Test this value: |-36/7 + 28/7|/|-24/7 +28/7] = 2
True
------------
Final Answer: x=-4 or x = -12/7
