how is it possible ?
x=(pi +3)/2
2x=pi +3
2x(pi 3)=(pi +3)(pi 3)
2pi*x 6x =(pi)^2 9
9 6x =(pi)^2 2pi*x
9 6x +x^2 =(pi)^2 2pi*x +x^2
(3 x)^2 =(pi x)^2
3x = pi x
pi =3

Everything looks legal, maybe when taking sq roots there is something that gets twisted.

look at the 3rd line if pi = 3 then both sides of equation = 0

Didn't consider the plus or minus when taking the square root. We get \[3x= \pm(\pix) \implies 3x=\pi  x~or~3x=x\pi\] The first equation generates the contradiction from the problem. The second generates the value of x given at the getgo.
