Question

Consider the equations y=1/√x and y=x−2.
The approximate solution of this system of equations is ____

Answer 1

replace y by 1/ sqrt x
1/ sqrt x = x - 2
square both sides
1 /x = (x-2)^2
can you continue/

Answer 2

1 is one of the roots
if we replace x by 1 in the above equation we get
1/1 = (-1)^2
1 = 1

Answer 3

but that does'nt fit the original equation so its not 1
