Hi ,
There is a simple task to calculate x from 1,5+0,5x = x. Simple!
1,5+0,5x=x
1,5=0,5x
x=3,0
However, colleague of mine come up with another answer:
1,5+0,5x=x /*2
3+x=2x /*(x+1)
3+4x+x^2=2x^2+2x /-(x^2)
3+4x=x^2+2x /-(5x)
3-x=x^2-3x
-(x-3)=x(x-3) / (x-3)
-1 = x
I know it is where he complicates things but above logic seems to be correct.
Where is mistake then ?
Thanks
K
