This equation has no solution

For C>0, the LHS equation equals 0
For C<0, the LHS equation equals 2C
For C=0, the LHS equation equals 0

Therefore, for no value of C does it equal 3

What about C = -3/2


-3/2 is not a solution. if you subsitute -3/2 in the equation C+|C|–|2C|=3
It results. -3=3 (thats not possible)

What is the source? As it mentions, it is a PS question. What are the options? I assume one of the options is "no solution".
