Solve: 4(x+2)-3x=x-6
You start by assuming the "x's" all mean the same number, and you are 
going to find that number.  You proceed as you were taught to proceed and
get:
4x+8 -3x = x-6
4x-3x-x= -6-8
0x = -14
0= -14
This is a contradiction that resulted from your assumption.
The assumption was wrong; there is no single number which
can replace "x".  
Answer: No solution
