It is a linear equation with only one unknown, although it looks strange because of the fractions, so lets get rid of the fractions:
<span>2/x = 1/4
</span>(2/x) = (<span>1/4)
</span>4*(2/x) = <span>1
8/x = 1
8 = 1*x
x = 8
that is the solution</span>
Probably a plane unless there's more to the question
