Answer by xcentaur(357) (Show Source): You can put this solution on YOUR website!
3.5x+4.6/x=1.2

multiplyin throughout by 'x'

3.5x^2+4.6=1.2x

taking all terms to left hand side we get,
3.5x^2-1.2x+4.6=0

(This is in standard form now of ax^2+bx+c=0)

Solved by pluggable solver: SOLVE quadratic equation with variable

Quadratic equation (in our case ) has the following solutons:

For these solutions to exist, the discriminant should not be a negative number.

First, we need to compute the discriminant : .

The discriminant -62.96 is less than zero. That means that there are no solutions among real numbers.

If you are a student of advanced school algebra and are aware about imaginary numbers, read on.

In the field of imaginary numbers, the square root of -62.96 is + or - .

The solution is
