Answer 1

First one is not linear because, if you square both the sides, it will be

x + 1/x + 2 = 3
multiply by x

x2 + 1 + 2x = 3x
x2 - x + 1 = 0

This is clearly not a linear equation. This is a quadratic equation.

Now, coming to second one, its √2x + √3y =0

This is a linear equation with two variables. Each variable is of degree 1, therefore its a linear equation. Don't get confused by √2, its irrational, but it doesn't play any role in deciding if an equation is linear or not.

Thank you

Answer 2

first one is quadratic and second one is linear
