oh are these 2 equations linked with each other, like is the value of n for the first equation = n for second? ;o

from 1st eqn\[x = 1  \sqrt{x}\] replacing 'x' with this value in \[x \sqrt{x}\] we get\[2x + (1  \sqrt{x})\sqrt{x}\]\[2x + (\sqrt{x}  x)\]\[x + \sqrt{x} = 1, as per eqn 1.\]

Don't know if it works... \[x+\sqrt x =1\] \[2x +x\sqrt x\]\[ = 2(1\sqrt x) + x\sqrt x\]\[ = 22\sqrt x + x\sqrt x\]\[ = 2  \sqrt x( 2 x)\]\[ = 2  \sqrt x( 2  (1\sqrt x))\]\[ = 2  \sqrt x( 1 +\sqrt x)\]\[ = 2  \sqrt x  x\]\[=2  (\sqrt x + x)\]\[=21\]\[=1\] Seems I've done something wrong :
